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.
Features
- Organizes all of your virtual environments in one place.
- Wrappers for managing your virtual environments (create, delete, copy).
- Use a single command to switch between environments.
- Tab completion for commands that take a virtual environment as argument.
- User-configurable hooks for all operations (see Per-User Customization).
- Plugin system for more creating sharable extensions (see Extending Virtualenvwrapper).
Introduction
The best way to explain the features virtualenvwrapper gives you is to show it in use.
First, some initialization steps. Most of this only needs to be done one time. You will want to add the command to source /usr/local/bin/virtualenvwrapper.sh to your shell startup file, changing the path to virtualenvwrapper.sh depending on where it was installed by pip.
$ pip install virtualenvwrapper
...
$ export WORKON_HOME=~/Envs
$ mkdir -p $WORKON_HOME
$ source /usr/local/bin/virtualenvwrapper.sh
$ mkvirtualenv env1

(env1)$ ls $WORKON_HOME
env1 hook.log
Now we can install some software into the environment.
(env1)$ pip install django

We can see the new package with lssitepackages:
(env1)$ lssitepackages
Django-1.1.1-py2.6.egg-info easy-install.pth
setuptools-0.6.10-py2.6.egg pip-0.6.3-py2.6.egg

Of course we are not limited to a single virtualenv:
(env1)$ ls $WORKON_HOME
env1 hook.log
(env1)$ mkvirtualenv env2

(env2)$ ls $WORKON_HOME
env1 env2 hook.log
Switch between environments with workon:
(env2)$ workon env1 (env1)$ echo $VIRTUAL_ENV /Users/dhellmann/Envs/env1 (env1)$
The workon command also includes tab completion for the environment names, and invokes customization scripts as an environment is activated or deactivated (see Per-User Customization).
(env1)$ echo 'cd $VIRTUAL_ENV' >> $WORKON_HOME/postactivate
(env1)$ workon env2
(env2)$ pwd
/Users/dhellmann/Envs/env2
postmkvirtualenv is run when a new environment is created, letting you automatically install commonly-used tools.
(env2)$ echo 'pip install sphinx' >> $WORKON_HOME/postmkvirtualenv
(env3)$ mkvirtualenv env3
New python executable in env3/bin/python

Through a combination of the existing functions defined by the core package (see Command Reference), third-party plugins (see Extending Virtualenvwrapper), and user-defined scripts (see Per-User Customization) virtualenvwrapper gives you a wide variety of opportunities to automate repetitive operations.
