Metadata-Version: 1.1 Name: virtualenv Version: 1.10.1 Summary: Virtual Python Environment builder Home-page: http://www.virtualenv.org Author: Jannis Leidel, Carl Meyer and Brian Rosner Author-email: python-virtualenv@groups.google.com License: MIT Description: What It Does ------------ ``virtualenv`` is a tool to create isolated Python environments. The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into ``/usr/lib/python2.7/site-packages`` (or whatever your platform's standard location is), it's easy to end up in a situation where you unintentionally upgrade an application that shouldn't be upgraded. Or more generally, what if you want to install an application *and leave it be*? If an application works, any change in its libraries or the versions of those libraries can break the application. Also, what if you can't install packages into the global ``site-packages`` directory? For instance, on a shared host. In all these cases, ``virtualenv`` can help you. It creates an environment that has its own installation directories, that doesn't share libraries with other virtualenv environments (and optionally doesn't access the globally installed libraries either). Installation ------------ .. warning:: We advise installing virtualenv-1.9 or greater. Prior to version 1.9, the pip included in virtualenv did not not download from PyPI over SSL. .. warning:: When using pip to install virtualenv, we advise using pip 1.3 or greater. Prior to version 1.3, pip did not not download from PyPI over SSL. .. warning:: We advise against using easy_install to install virtualenv when using setuptools < 0.9.7, because easy_install didn't download from PyPI over SSL and was broken in some subtle ways. To install globally with `pip` (if you have pip 1.3 or greater installed globally): :: $ [sudo] pip install virtualenv Or to get the latest unreleased dev version: :: $ [sudo] pip install https://github.com/pypa/virtualenv/tarball/develop To install globally from source: :: $ curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz $ tar xvfz virtualenv-X.X.tar.gz $ cd virtualenv-X.X $ [sudo] python setup.py install To *use* locally from source: :: $ curl -O https://pypi.python.org/packages/source/v/virtualenv/virtualenv-X.X.tar.gz $ tar xvfz virtualenv-X.X.tar.gz $ cd virtualenv-X.X $ python virtualenv.py myVE .. note:: The ``virtualenv.py`` script is *not* supported if run without the necessary pip/setuptools/virtualenv distributions available locally. All of the installation methods above include a ``virtualenv_support`` directory alongside ``virtualenv.py`` which contains a complete set of pip and setuptools distributions, and so are fully supported. Usage ----- The basic usage is:: $ virtualenv ENV This creates ``ENV/lib/pythonX.X/site-packages``, where any libraries you install will go. It also creates ``ENV/bin/python``, which is a Python interpreter that uses this environment. Anytime you use that interpreter (including when a script has ``#!/path/to/ENV/bin/python`` in it) the libraries in that environment will be used. It also installs either `Setuptools `_ into the environment. .. note:: Virtualenv (<1.10) used to provide a ``--distribute`` option to use the setuptools fork Distribute_. Since Distribute has been merged back into setuptools this option is now no-op, it will always use the improved setuptools releases. A new virtualenv also includes the `pip `_ installer, so you can use ``ENV/bin/pip`` to install additional packages into the environment. .. _Distribute: https://pypi.python.org/pypi/distribute activate script ~~~~~~~~~~~~~~~ In a newly created virtualenv there will be a ``bin/activate`` shell script. For Windows systems, activation scripts are provided for CMD.exe and Powershell. On Posix systems you can do:: $ source bin/activate This will change your ``$PATH`` so its first entry is the virtualenv's ``bin/`` directory. (You have to use ``source`` because it changes your shell environment in-place.) This is all it does; it's purely a convenience. If you directly run a script or the python interpreter from the virtualenv's ``bin/`` directory (e.g. ``path/to/env/bin/pip`` or ``/path/to/env/bin/python script.py``) there's no need for activation. After activating an environment you can use the function ``deactivate`` to undo the changes to your ``$PATH``. The ``activate`` script will also modify your shell prompt to indicate which environment is currently active. You can disable this behavior, which can be useful if you have your own custom prompt that already displays the active environment name. To do so, set the ``VIRTUAL_ENV_DISABLE_PROMPT`` environment variable to any non-empty value before running the ``activate`` script. On Windows you just do:: > \path\to\env\Scripts\activate And type `deactivate` to undo the changes. Based on your active shell (CMD.exe or Powershell.exe), Windows will use either activate.bat or activate.ps1 (as appropriate) to activate the virtual environment. If using Powershell, see the notes about code signing below. .. note:: If using Powershell, the ``activate`` script is subject to the `execution policies`_ on the system. By default on Windows 7, the system's excution policy is set to ``Restricted``, meaning no scripts like the ``activate`` script are allowed to be executed. But that can't stop us from changing that slightly to allow it to be executed. In order to use the script, you have to relax your system's execution policy to ``AllSigned``, meaning all scripts on the system must be digitally signed to be executed. Since the virtualenv activation script is signed by one of the authors (Jannis Leidel) this level of the execution policy suffices. As an administrator run:: PS C:\> Set-ExecutionPolicy AllSigned Then you'll be asked to trust the signer, when executing the script. You will be prompted with the following:: PS C:\> virtualenv .\foo New python executable in C:\foo\Scripts\python.exe Installing setuptools................done. Installing pip...................done. PS C:\> .\foo\scripts\activate Do you want to run software from this untrusted publisher? File C:\foo\scripts\activate.ps1 is published by E=jannis@leidel.info, CN=Jannis Leidel, L=Berlin, S=Berlin, C=DE, Description=581796-Gh7xfJxkxQSIO4E0 and is not trusted on your system. Only run scripts from trusted publishers. [V] Never run [D] Do not run [R] Run once [A] Always run [?] Help (default is "D"):A (foo) PS C:\> If you select ``[A] Always Run``, the certificate will be added to the Trusted Publishers of your user account, and will be trusted in this user's context henceforth. If you select ``[R] Run Once``, the script will be run, but you will be prometed on a subsequent invocation. Advanced users can add the signer's certificate to the Trusted Publishers of the Computer account to apply to all users (though this technique is out of scope of this document). Alternatively, you may relax the system execution policy to allow running of local scripts without verifying the code signature using the following:: PS C:\> Set-ExecutionPolicy RemoteSigned Since the ``activate.ps1`` script is generated locally for each virtualenv, it is not considered a remote script and can then be executed. .. _`execution policies`: http://technet.microsoft.com/en-us/library/dd347641.aspx The ``--system-site-packages`` Option ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ If you build with ``virtualenv --system-site-packages ENV``, your virtual environment will inherit packages from ``/usr/lib/python2.7/site-packages`` (or wherever your global site-packages directory is). This can be used if you have control over the global site-packages directory, and you want to depend on the packages there. If you want isolation from the global system, do not use this flag. Environment variables and configuration files ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ virtualenv can not only be configured by passing command line options such as ``--python`` but also by two other means: - Environment variables Each command line option is automatically used to look for environment variables with the name format ``VIRTUALENV_``. That means the name of the command line options are capitalized and have dashes (``'-'``) replaced with underscores (``'_'``). For example, to automatically use a custom Python binary instead of the one virtualenv is run with you can also set an environment variable:: $ export VIRTUALENV_PYTHON=/opt/python-3.3/bin/python $ virtualenv ENV It's the same as passing the option to virtualenv directly:: $ virtualenv --python=/opt/python-3.3/bin/python ENV This also works for appending command line options, like ``--find-links``. Just leave an empty space between the passsed values, e.g.:: $ export VIRTUALENV_EXTRA_SEARCH_DIR="/path/to/dists /path/to/other/dists" $ virtualenv ENV is the same as calling:: $ virtualenv --extra-search-dir=/path/to/dists --extra-search-dir=/path/to/other/dists ENV - Config files virtualenv also looks for a standard ini config file. On Unix and Mac OS X that's ``$HOME/.virtualenv/virtualenv.ini`` and on Windows, it's ``%APPDATA%\virtualenv\virtualenv.ini``. The names of the settings are derived from the long command line option, e.g. the option ``--python`` would look like this:: [virtualenv] python = /opt/python-3.3/bin/python Appending options like ``--extra-search-dir`` can be written on multiple lines:: [virtualenv] extra-search-dir = /path/to/dists /path/to/other/dists Please have a look at the output of ``virtualenv --help`` for a full list of supported options. Windows Notes ~~~~~~~~~~~~~ Some paths within the virtualenv are slightly different on Windows: scripts and executables on Windows go in ``ENV\Scripts\`` instead of ``ENV/bin/`` and libraries go in ``ENV\Lib\`` rather than ``ENV/lib/``. To create a virtualenv under a path with spaces in it on Windows, you'll need the `win32api `_ library installed. PyPy Support ~~~~~~~~~~~~ Beginning with virtualenv version 1.5 `PyPy `_ is supported. To use PyPy 1.4 or 1.4.1, you need a version of virtualenv >= 1.5. To use PyPy 1.5, you need a version of virtualenv >= 1.6.1. Creating Your Own Bootstrap Scripts ----------------------------------- While this creates an environment, it doesn't put anything into the environment. Developers may find it useful to distribute a script that sets up a particular environment, for example a script that installs a particular web application. To create a script like this, call ``virtualenv.create_bootstrap_script(extra_text)``, and write the result to your new bootstrapping script. Here's the documentation from the docstring: Creates a bootstrap script, which is like this script but with extend_parser, adjust_options, and after_install hooks. This returns a string that (written to disk of course) can be used as a bootstrap script with your own customizations. The script will be the standard virtualenv.py script, with your extra text added (your extra text should be Python code). If you include these functions, they will be called: ``extend_parser(optparse_parser)``: You can add or remove options from the parser here. ``adjust_options(options, args)``: You can change options here, or change the args (if you accept different kinds of arguments, be sure you modify ``args`` so it is only ``[DEST_DIR]``). ``after_install(options, home_dir)``: After everything is installed, this function is called. This is probably the function you are most likely to use. An example would be:: def after_install(options, home_dir): if sys.platform == 'win32': bin = 'Scripts' else: bin = 'bin' subprocess.call([join(home_dir, bin, 'easy_install'), 'MyPackage']) subprocess.call([join(home_dir, bin, 'my-package-script'), 'setup', home_dir]) This example immediately installs a package, and runs a setup script from that package. Bootstrap Example ~~~~~~~~~~~~~~~~~ Here's a more concrete example of how you could use this:: import virtualenv, textwrap output = virtualenv.create_bootstrap_script(textwrap.dedent(""" import os, subprocess def after_install(options, home_dir): etc = join(home_dir, 'etc') if not os.path.exists(etc): os.makedirs(etc) subprocess.call([join(home_dir, 'bin', 'easy_install'), 'BlogApplication']) subprocess.call([join(home_dir, 'bin', 'paster'), 'make-config', 'BlogApplication', join(etc, 'blog.ini')]) subprocess.call([join(home_dir, 'bin', 'paster'), 'setup-app', join(etc, 'blog.ini')]) """)) f = open('blog-bootstrap.py', 'w').write(output) Another example is available `here `_. Using Virtualenv without ``bin/python`` --------------------------------------- Sometimes you can't or don't want to use the Python interpreter created by the virtualenv. For instance, in a `mod_python `_ or `mod_wsgi `_ environment, there is only one interpreter. Luckily, it's easy. You must use the custom Python interpreter to *install* libraries. But to *use* libraries, you just have to be sure the path is correct. A script is available to correct the path. You can setup the environment like:: activate_this = '/path/to/env/bin/activate_this.py' execfile(activate_this, dict(__file__=activate_this)) This will change ``sys.path`` and even change ``sys.prefix``, but also allow you to use an existing interpreter. Items in your environment will show up first on ``sys.path``, before global items. However, global items will always be accessible (as if the ``--system-site-packages`` flag had been used in creating the environment, whether it was or not). Also, this cannot undo the activation of other environments, or modules that have been imported. You shouldn't try to, for instance, activate an environment before a web request; you should activate *one* environment as early as possible, and not do it again in that process. Making Environments Relocatable ------------------------------- Note: this option is somewhat experimental, and there are probably caveats that have not yet been identified. .. warning:: The ``--relocatable`` option currently has a number of issues, and is not guaranteed to work in all circumstances. It is possible that the option will be deprecated in a future version of ``virtualenv``. Normally environments are tied to a specific path. That means that you cannot move an environment around or copy it to another computer. You can fix up an environment to make it relocatable with the command:: $ virtualenv --relocatable ENV This will make some of the files created by setuptools use relative paths, and will change all the scripts to use ``activate_this.py`` instead of using the location of the Python interpreter to select the environment. **Note:** scripts which have been made relocatable will only work if the virtualenv is activated, specifically the python executable from the virtualenv must be the first one on the system PATH. Also note that the activate scripts are not currently made relocatable by ``virtualenv --relocatable``. **Note:** you must run this after you've installed *any* packages into the environment. If you make an environment relocatable, then install a new package, you must run ``virtualenv --relocatable`` again. Also, this **does not make your packages cross-platform**. You can move the directory around, but it can only be used on other similar computers. Some known environmental differences that can cause incompatibilities: a different version of Python, when one platform uses UCS2 for its internal unicode representation and another uses UCS4 (a compile-time option), obvious platform changes like Windows vs. Linux, or Intel vs. ARM, and if you have libraries that bind to C libraries on the system, if those C libraries are located somewhere different (either different versions, or a different filesystem layout). If you use this flag to create an environment, currently, the ``--system-site-packages`` option will be implied. The ``--extra-search-dir`` option --------------------------------- .. note:: Currently, this feature only partially works for pip, and not at all for setuptools. For details, see `Issue #327 `_ This option allows you to provide your own versions of setuptools and/or pip on the filesystem, and tell virtualenv to use those distributions instead of the ones in ``virtualenv_support``. To use this feature, pass one or more ``--extra-search-dir`` options to virtualenv like this:: $ virtualenv --extra-search-dir=/path/to/distributions ENV The ``/path/to/distributions`` path should point to a directory that contains setuptools and/or pip distributions. Setuptools distributions must be ``.egg`` files; pip distributions should be `.tar.gz` source distributions. If no satisfactory local distributions are found, virtualenv will fail. Virtualenv will never download packages. The distribution lookup is done in the following locations, with the most recent version found used: #. The current directory. #. The directory where virtualenv.py is located. #. A ``virtualenv_support`` directory relative to the directory where virtualenv.py is located. #. If the file being executed is not named virtualenv.py (i.e. is a boot script), a ``virtualenv_support`` directory relative to wherever virtualenv.py is actually installed. Compare & Contrast with Alternatives ------------------------------------ There are several alternatives that create isolated environments: * ``workingenv`` (which I do not suggest you use anymore) is the predecessor to this library. It used the main Python interpreter, but relied on setting ``$PYTHONPATH`` to activate the environment. This causes problems when running Python scripts that aren't part of the environment (e.g., a globally installed ``hg`` or ``bzr``). It also conflicted a lot with Setuptools. * `virtual-python `_ is also a predecessor to this library. It uses only symlinks, so it couldn't work on Windows. It also symlinks over the *entire* standard library and global ``site-packages``. As a result, it won't see new additions to the global ``site-packages``. This script only symlinks a small portion of the standard library into the environment, and so on Windows it is feasible to simply copy these files over. Also, it creates a new/empty ``site-packages`` and also adds the global ``site-packages`` to the path, so updates are tracked separately. This script also installs Setuptools automatically, saving a step and avoiding the need for network access. * `zc.buildout `_ doesn't create an isolated Python environment in the same style, but achieves similar results through a declarative config file that sets up scripts with very particular packages. As a declarative system, it is somewhat easier to repeat and manage, but more difficult to experiment with. ``zc.buildout`` includes the ability to setup non-Python systems (e.g., a database server or an Apache instance). I *strongly* recommend anyone doing application development or deployment use one of these tools. Contributing ------------ Refer to the `contributing to pip`_ documentation - it applies equally to virtualenv, except that virtualenv issues should filed on the `virtualenv repo`_ at GitHub. Virtualenv's release schedule is tied to pip's -- each time there's a new pip release, there will be a new virtualenv release that bundles the new version of pip. Files in the `virtualenv_embedded/` subdirectory are embedded into `virtualenv.py` itself as base64-encoded strings (in order to support single-file use of `virtualenv.py` without installing it). If your patch changes any file in `virtualenv_embedded/`, run `bin/rebuild-script.py` to update the embedded version of that file in `virtualenv.py`; commit that and submit it as part of your patch / pull request. .. _contributing to pip: http://www.pip-installer.org/en/latest/contributing.html .. _virtualenv repo: https://github.com/pypa/virtualenv/ Running the tests ~~~~~~~~~~~~~~~~~ Virtualenv's test suite is small and not yet at all comprehensive, but we aim to grow it. The easy way to run tests (handles test dependencies automatically):: $ python setup.py test If you want to run only a selection of the tests, you'll need to run them directly with nose instead. Create a virtualenv, and install required packages:: $ pip install nose mock Run nosetests:: $ nosetests Or select just a single test file to run:: $ nosetests tests.test_virtualenv Other Documentation and Links ----------------------------- * James Gardner has written a tutorial on using `virtualenv with Pylons `_. * `Blog announcement `_. * Doug Hellmann wrote a description of his `command-line work flow using virtualenv (virtualenvwrapper) `_ including some handy scripts to make working with multiple environments easier. He also wrote `an example of using virtualenv to try IPython `_. * Chris Perkins created a `showmedo video including virtualenv `_. * `Using virtualenv with mod_wsgi `_. * `virtualenv commands `_ for some more workflow-related tools around virtualenv. Status and License ------------------ ``virtualenv`` is a successor to `workingenv `_, and an extension of `virtual-python `_. It was written by Ian Bicking, sponsored by the `Open Planning Project `_ and is now maintained by a `group of developers `_. It is licensed under an `MIT-style permissive license `_. Changes & News -------------- .. warning:: Python bugfix releases 2.6.8, 2.7.3, 3.1.5 and 3.2.3 include a change that will cause "import random" to fail with "cannot import name urandom" on any virtualenv created on a Unix host with an earlier release of Python 2.6/2.7/3.1/3.2, if the underlying system Python is upgraded. This is due to the fact that a virtualenv uses the system Python's standard library but contains its own copy of the Python interpreter, so an upgrade to the system Python results in a mismatch between the version of the Python interpreter and the version of the standard library. It can be fixed by removing ``$ENV/bin/python`` and re-running virtualenv on the same target directory with the upgraded Python. 1.10.1 (2013-08-07) ~~~~~~~~~~~~~~~~~~~ * **New Signing Key** Release 1.10.1 is using a different key than normal with fingerprint: 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA * Upgraded pip to v1.4.1 * Upgraded setuptools to v0.9.8 1.10 (2013-07-23) ~~~~~~~~~~~~~~~~~ * **BACKWARDS INCOMPATIBLE** Dropped support for Python 2.5. The minimum supported Python version is now Python 2.6. * **BACKWARDS INCOMPATIBLE** Using ``virtualenv.py`` as an isolated script (i.e. without an associated ``virtualenv_support`` directory) is no longer supported for security reasons and will fail with an error. Along with this, ``--never-download`` is now always pinned to ``True``, and is only being maintained in the short term for backward compatibility (Pull #412). * **IMPORTANT** Switched to the new setuptools (v0.9.7) which has been merged with Distribute_ again and works for Python 2 and 3 with one codebase. The ``--distribute`` and ``--setuptools`` options are now no-op. * Updated to pip 1.4. * Added support for PyPy3k * Added the option to use a version number with the ``-p`` option to get the system copy of that Python version (Windows only) * Removed embedded ``ez_setup.py``, ``distribute_setup.py`` and ``distribute_from_egg.py`` files as part of switching to merged setuptools. * Fixed ``--relocatable`` to work better on Windows. * Fixed issue with readline on Windows. .. _Distribute: https://pypi.python.org/pypi/distribute 1.9.1 (2013-03-08) ~~~~~~~~~~~~~~~~~~ * Updated to pip 1.3.1 that fixed a major backward incompatible change of parsing URLs to externally hosted packages that got accidentily included in pip 1.3. 1.9 (2013-03-07) ~~~~~~~~~~~~~~~~ * Unset VIRTUAL_ENV environment variable in deactivate.bat (Pull #364) * Upgraded distribute to 0.6.34. * Added ``--no-setuptools`` and ``--no-pip`` options (Pull #336). * Fixed Issue #373. virtualenv-1.8.4 was failing in cygwin (Pull #382). * Fixed Issue #378. virtualenv is now "multiarch" aware on debian/ubuntu (Pull #379). * Fixed issue with readline module path on pypy and OSX (Pull #374). * Made 64bit detection compatible with Python 2.5 (Pull #393). 1.8.4 (2012-11-25) ~~~~~~~~~~~~~~~~~~ * Updated distribute to 0.6.31. This fixes #359 (numpy install regression) on UTF-8 platforms, and provides a workaround on other platforms: ``PYTHONIOENCODING=utf8 pip install numpy``. * When installing virtualenv via curl, don't forget to filter out arguments the distribute setup script won't understand. Fixes #358. * Added some more integration tests. * Removed the unsupported embedded setuptools egg for Python 2.4 to reduce file size. 1.8.3 (2012-11-21) ~~~~~~~~~~~~~~~~~~ * Fixed readline on OS X. Thanks minrk * Updated distribute to 0.6.30 (improves our error reporting, plus new distribute features and fixes).

Huge thanks to Vinay Sajip and Vitaly Babiy. * Fixed creation of virtualenvs on Mac OS X when standard library modules (readline) are installed outside the standard library. * Updated bundled pip to 1.0. 1.5.2 ~~~~~ * Moved main repository to Github: https://github.com/pypa/virtualenv * Transferred primary maintenance from Ian to Jannis Leidel, Carl Meyer and Brian Rosner * Fixed a few more pypy related bugs. * Updated bundled pip to 0.8.2. * Handed project over to new team of maintainers. * Moved virtualenv to Github at https://github.com/pypa/virtualenv 1.5.1 ~~~~~ * Added ``_weakrefset`` requirement for Python 2.7.1. * Fixed Windows regression in 1.5 1.5 ~~~ * Include pip 0.8.1. * Add support for PyPy. * Uses a proper temporary dir when installing environment requirements. * Add ``--prompt`` option to be able to override the default prompt prefix. * Fix an issue with ``--relocatable`` on Windows. * Fix issue with installing the wrong version of distribute. * Add fish and csh activate scripts. 1.4.9 ~~~~~ * Include pip 0.7.2 1.4.8 ~~~~~ * Fix for Mac OS X Framework builds that use ``--universal-archs=intel`` * Fix ``activate_this.py`` on Windows. * Allow ``$PYTHONHOME`` to be set, so long as you use ``source bin/activate`` it will get unset; if you leave it set and do not activate the environment it will still break the environment. * Include pip 0.7.1 1.4.7 ~~~~~ * Include pip 0.7 1.4.6 ~~~~~ * Allow ``activate.sh`` to skip updating the prompt (by setting ``$VIRTUAL_ENV_DISABLE_PROMPT``). 1.4.5 ~~~~~ * Include pip 0.6.3 * Fix ``activate.bat`` and ``deactivate.bat`` under Windows when ``PATH`` contained a parenthesis 1.4.4 ~~~~~ * Include pip 0.6.2 and Distribute 0.6.10 * Create the ``virtualenv`` script even when Setuptools isn't installed * Fix problem with ``virtualenv --relocate`` when ``bin/`` has subdirectories (e.g., ``bin/.svn/``); from Alan Franzoni. * If you set ``$VIRTUALENV_DISTRIBUTE`` then virtualenv will use Distribute by default (so you don't have to remember to use ``--distribute``). 1.4.3 ~~~~~ * Include pip 0.6.1 1.4.2 ~~~~~ * Fix pip installation on Windows * Fix use of stand-alone ``virtualenv.py`` (and boot scripts) * Exclude ~/.local (user site-packages) from environments when using ``--no-site-packages`` 1.4.1 ~~~~~ * Include pip 0.6 1.4 ~~~ * Updated setuptools to 0.6c11 * Added the --distribute option * Fixed packaging problem of support-files 1.3.4 ~~~~~ * Virtualenv now copies the actual embedded Python binary on Mac OS X to fix a hang on Snow Leopard (10.6). * Fail more gracefully on Windows when ``win32api`` is not installed. * Fix site-packages taking precedent over Jython's ``__classpath__`` and also specially handle the new ``__pyclasspath__`` entry in ``sys.path``. * Now copies Jython's ``registry`` file to the virtualenv if it exists. * Better find libraries when compiling extensions on Windows. * Create ``Scripts\pythonw.exe`` on Windows. * Added support for the Debian/Ubuntu ``/usr/lib/pythonX.Y/dist-packages`` directory. * Set ``distutils.sysconfig.get_config_vars()['LIBDIR']`` (based on ``sys.real_prefix``) which is reported to help building on Windows. * Make ``deactivate`` work on ksh * Fixes for ``--python``: make it work with ``--relocatable`` and the symlink created to the exact Python version. 1.3.3 ~~~~~ * Use Windows newlines in ``activate.bat``, which has been reported to help when using non-ASCII directory names. * Fixed compatibility with Jython 2.5b1. * Added a function ``virtualenv.install_python`` for more fine-grained access to what ``virtualenv.create_environment`` does. * Fix `a problem `_ with Windows and paths that contain spaces. * If ``/path/to/env/.pydistutils.cfg`` exists (or ``/path/to/env/pydistutils.cfg`` on Windows systems) then ignore ``~/.pydistutils.cfg`` and use that other file instead. * Fix ` a problem `_ picking up some ``.so`` libraries in ``/usr/local``. 1.3.2 ~~~~~ * Remove the ``[install] prefix = ...`` setting from the virtualenv ``distutils.cfg`` -- this has been causing problems for a lot of people, in rather obscure ways. * If you use a boot script it will attempt to import ``virtualenv`` and find a pre-downloaded Setuptools egg using that. * Added platform-specific paths, like ``/usr/lib/pythonX.Y/plat-linux2`` 1.3.1 ~~~~~ * Real Python 2.6 compatibility. Backported the Python 2.6 updates to ``site.py``, including `user directories `_ (this means older versions of Python will support user directories, whether intended or not). * Always set ``[install] prefix`` in ``distutils.cfg`` -- previously on some platforms where a system-wide ``distutils.cfg`` was present with a ``prefix`` setting, packages would be installed globally (usually in ``/usr/local/lib/pythonX.Y/site-packages``). * Sometimes Cygwin seems to leave ``.exe`` off ``sys.executable``; a workaround is added. * Fix ``--python`` option. * Fixed handling of Jython environments that use a jython-complete.jar. 1.3 ~~~ * Update to Setuptools 0.6c9 * Added an option ``virtualenv --relocatable EXISTING_ENV``, which will make an existing environment "relocatable" -- the paths will not be absolute in scripts, ``.egg-info`` and ``.pth`` files. This may assist in building environments that can be moved and copied. You have to run this *after* any new packages installed. * Added ``bin/activate_this.py``, a file you can use like ``execfile("path_to/activate_this.py", dict(__file__="path_to/activate_this.py"))`` -- this will activate the environment in place, similar to what `the mod_wsgi example does `_. * For Mac framework builds of Python, the site-packages directory ``/Library/Python/X.Y/site-packages`` is added to ``sys.path``, from Andrea Rech. * Some platform-specific modules in Macs are added to the path now (``plat-darwin/``, ``plat-mac/``, ``plat-mac/lib-scriptpackages``), from Andrea Rech. * Fixed a small Bashism in the ``bin/activate`` shell script. * Added ``__future__`` to the list of required modules, for Python 2.3. You'll still need to backport your own ``subprocess`` module. * Fixed the ``__classpath__`` entry in Jython's ``sys.path`` taking precedent over virtualenv's libs. 1.2 ~~~ * Added a ``--python`` option to select the Python interpreter. * Add ``warnings`` to the modules copied over, for Python 2.6 support. * Add ``sets`` to the module copied over for Python 2.3 (though Python 2.3 still probably doesn't work). 1.1.1 ~~~~~ * Added support for Jython 2.5. 1.1 ~~~ * Added support for Python 2.6. * Fix a problem with missing ``DLLs/zlib.pyd`` on Windows. Create * ``bin/python`` (or ``bin/python.exe``) even when you run virtualenv with an interpreter named, e.g., ``python2.4`` * Fix MacPorts Python * Added --unzip-setuptools option * Update to Setuptools 0.6c8 * If the current directory is not writable, run ez_setup.py in ``/tmp`` * Copy or symlink over the ``include`` directory so that packages will more consistently compile. 1.0 ~~~ * Fix build on systems that use ``/usr/lib64``, distinct from ``/usr/lib`` (specifically CentOS x64). * Fixed bug in ``--clear``. * Fixed typos in ``deactivate.bat``. * Preserve ``$PYTHONPATH`` when calling subprocesses. 0.9.2 ~~~~~ * Fix include dir copying on Windows (makes compiling possible). * Include the main ``lib-tk`` in the path. * Patch ``distutils.sysconfig``: ``get_python_inc`` and ``get_python_lib`` to point to the global locations. * Install ``distutils.cfg`` before Setuptools, so that system customizations of ``distutils.cfg`` won't effect the installation. * Add ``bin/pythonX.Y`` to the virtualenv (in addition to ``bin/python``). * Fixed an issue with Mac Framework Python builds, and absolute paths (from Ronald Oussoren). 0.9.1 ~~~~~ * Improve ability to create a virtualenv from inside a virtualenv. * Fix a little bug in ``bin/activate``. * Actually get ``distutils.cfg`` to work reliably. 0.9 ~~~ * Added ``lib-dynload`` and ``config`` to things that need to be copied over in an environment. * Copy over or symlink the ``include`` directory, so that you can build packages that need the C headers. * Include a ``distutils`` package, so you can locally update ``distutils.cfg`` (in ``lib/pythonX.Y/distutils/distutils.cfg``). * Better avoid downloading Setuptools, and hitting PyPI on environment creation. * Fix a problem creating a ``lib64/`` directory. * Should work on MacOSX Framework builds (the default Python installations on Mac). Thanks to Ronald Oussoren. 0.8.4 ~~~~~ * Windows installs would sometimes give errors about ``sys.prefix`` that were inaccurate. * Slightly prettier output. 0.8.3 ~~~~~ * Added support for Windows. 0.8.2 ~~~~~ * Give a better warning if you are on an unsupported platform (Mac Framework Pythons, and Windows). * Give error about running while inside a workingenv. * Give better error message about Python 2.3. 0.8.1 ~~~~~ Fixed packaging of the library. 0.8 ~~~ Initial release.
