Changes & News
1.7.1 (2012-02-16)
* Update embedded pip to version 1.1.
* Fix `--relocatable` under Python 3. Thanks Doug Hellmann.
* Added environ PATH modification to Thanks Doug
Napoleone. Fixes #14.
* Support creating virtualenvs directly from a Python build directory on
Windows. Thanks CBWhiz. Fixes #139.
* Use non-recursive symlinks to fix things up for posix_local install
scheme. Thanks michr.
* Made activate script available for use with msys and cygwin on Windows.
Thanks Greg Haskins, Cliff Xuan, Jonathan Griffin and Doug Napoleone.
Fixes #176.
* Fixed creation of virtualenvs on Windows when Python is not installed for
all users. Thanks Anatoly Techtonik for report and patch and Doug
Napoleone for testing and confirmation. Fixes #87.
* Fixed creation of virtualenvs using -p in installs where some modules
that ought to be in the standard library (e.g. `readline`) are actually
installed in `site-packages` next to ``. Thanks Greg Haskins
for report and fix. Fixes #167.
* Added activation script for Powershell (signed by Jannis Leidel). Many
thanks to Jason R. Coombs.
1.7 (2011-11-30)
* Gave user-provided ``--extra-search-dir`` priority over default dirs for
finding setuptools/distribute (it already had priority for finding pip).
Thanks Ethan Jucovy.
* Updated embedded Distribute release to 0.6.24. Thanks Alex Gronholm.
* Made ``--no-site-packages`` behavior the default behavior. The
``--no-site-packages`` flag is still permitted, but displays a warning when
used. Thanks Chris McDonough.
* New flag: ``--system-site-packages``; this flag should be passed to get the
previous default global-site-package-including behavior back.
* Added ability to set command options as environment variables and options
in a ``virtualenv.ini`` file.
* Fixed various encoding related issues with paths. Thanks Gunnlaugur Thor Briem.
* Made ```` script executable.
1.6.4 (2011-07-21)
* Restored ability to run on Python 2.4, too.
1.6.3 (2011-07-16)

* Updated embedded pip release to 1.0.2.
* Fixed #141 - Be smarter about finding pkg_resources when using the
non-default Python intepreter (by using the ``-p`` option).
* Fixed #112 - Fixed path in docs.
* Fixed #109 - Corrected doctests of a Logger method.
* Fixed #118 - Fixed creating virtualenvs on platforms that use the
"posix_local" install scheme, such as Ubuntu with Python 2.7.
* Add missing library to Python 3 virtualenvs (``_dummy_thread``).
1.6.1 (2011-04-30)
* Start to use git-flow.
* Added support for PyPy 1.5
* Fixed #121 -- added sanity-checking of the -p argument. Thanks Paul Nasrat.

* 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.
* Moved main repository to Github:
* Transferred primary maintenance from Ian to Jannis Leidel, Carl Meyer and Brian Rosner

* Fix issue with installing the wrong version of distribute.
* Add fish and csh activate scripts.
* Include pip 0.7.2
* Fix for Mac OS X Framework builds that use
* Fix ```` on Windows.
* Allow ``$PYTHONHOME`` to be set, so long as you use ``source
bin/activate`` it will get unset; if you leave it set and do not
activate the environment it will still break the environment.
* Include pip 0.7.1
* Include pip 0.7
* Allow ```` to skip updating the prompt (by setting
* Include pip 0.6.3
* Fix ``activate.bat`` and ``deactivate.bat`` under Windows when
``PATH`` contained a parenthesis
* Include pip 0.6.2 and Distribute 0.6.10
* Create the ``virtualenv`` script even when Setuptools isn't
* Fix problem with ``virtualenv --relocate`` when ``bin/`` has
subdirectories (e.g., ``bin/.svn/``); from Alan Franzoni.
* If you set ``$VIRTUALENV_USE_DISTRIBUTE`` then virtualenv will use
Distribute by default (so you don't have to remember to use
* Include pip 0.6.1
* Fix pip installation on Windows
* Fix use of stand-alone ```` (and boot scripts)
* Exclude ~/.local (user site-packages) from environments when using
* Include pip 0.6
* Updated setuptools to 0.6c11
* Added the --distribute option
* Fixed packaging problem of support-files
* 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
* 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.
* 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``.
* 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 <./index.html#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``
* Real Python 2.6 compatibility. Backported the Python 2.6 updates to
````, 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
* 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/``, a file you can use like
dict(__file__="path_to/"))`` -- 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.
* 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).
* Added support for Jython 2.5.
* 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 in ``/tmp``
* Copy or symlink over the ``include`` directory so that packages will
more consistently compile.
* 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.
* 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
* Fixed an issue with Mac Framework Python builds, and absolute paths
(from Ronald Oussoren).
* Improve ability to create a virtualenv from inside a virtualenv.
* Fix a little bug in ``bin/activate``.
* Actually get ``distutils.cfg`` to work reliably.
* 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
* Fix a problem creating a ``lib64/`` directory.
* Should work on MacOSX Framework builds (the default Python
installations on Mac). Thanks to Ronald Oussoren.
* Windows installs would sometimes give errors about ``sys.prefix`` that
were inaccurate.
* Slightly prettier output.
* Added support for Windows.
* 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.
Fixed packaging of the library.
Initial release. Everything is changed and new!
