virtualenvwrapper 4.3

Enhancements to virtualenv

virtualenvwrapper is a set of extensions to Ian Bicking’s virtualenv tool. The extensions include wrappers for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies.

Warning: The 4.x release includes some potentially incompatible changes for extensions from 3.x. The python modules for extensions are now always run with PWD=$WORKON_HOME (previously the value of PWD varied depending on the hook). The shell portion of any hook (anything sourced by the user’s shell when the hook is run) is still run in the same place as before.

Features

1. Organizes all of your virtual environments in one place.

2. Wrappers for creating, copying and deleting environments, including user-configurable hooks.

3. Use a single command to switch between environments.

4. Tab completion for commands that take a virtual environment as argument.

5. User-configurable hooks for all operations.

6. Plugin system for more creating sharable extensions.

Rich Leland has created a short screencast showing off the features of virtualenvwrapper.

Installation

See the project documentation for installation and setup instructions.

Supported Shells

virtualenvwrapper is a set of shell functions defined in Bourne shell compatible syntax. It is tested under bash, ksh, and zsh. It may work with other shells, so if you find that it does work with a shell not listed here please let me know. If you can modify it to work with another shell, without completely rewriting it, send a pull request through the bitbucket project page. If you write a clone to work with an incompatible shell, let me know and I will link to it from this page.

Python Versions

virtualenvwrapper is tested under Python 2.6 - 3.3.

Support

Report bugs via the bug tracker on BitBucket.

Shell Aliases

Since virtualenvwrapper is largely a shell script, it uses shell commands for a lot of its actions. If your environment makes heavy use of shell aliases or other customizations, you may encounter issues. Before reporting bugs in the bug tracker, please test without your aliases enabled. If you can identify the alias causing the problem, that will help make virtualenvwrapper more robust.
