WARNING: This virtualenv package has been deprecated!

I haven't maintained in a long time since I use docker and LXC for a better virtual environment for my development purposes that provides stronger isolation, first-class network interfaces, and support for non-python stacks.

If you still want to work with virtualenv there are at least 3 newer, actively maintained packages available on MELPA that are superior to my old one that have taken its place:

This is a minor mode for setting the virtual environment for the Python shell using virtualenv and supports both python-mode.el and python.el. This minor mode was inspired by an earlier implementation by Jesse Legg and Jeremiah Dodds, however this code is a complete re-write with a GPLv3 license consistent with GNU Emacs and python-mode.el.

There are two ways to use virtualenv.

1) The quickest way to get started is to simply type: M-x virtualenv-workon Which will prompt you to enter the name of a directory in ~/.virtualenvs that contains your chosen environment. You can hit tab to show the available completions.

You'll know that you're in virtualenv mode now when you see the name of the virtualenv you selected in brackets. So if I were to select my turbogears environment that I call tg2.1 then I would see [tg2.1] appear in the mode line. To make sure you're new python shell is set up correctly you can try running this little snippet of python code:

 import os, sys
 print os.environ
 print sys.path

2) The recommended way to use virtualenv minor mode is to use a .dir-locals.el file in the root of your project directory.

REQUIRES: Emacs 23.1 or higher.

There are two buffer-local variables that you can set for virtualenv as shown in this example:

in file /path/to/project/.dir-locals.el: ((nil . ((virtualenv-workon . “tg2.1”) (virtualenv-default-directory . “/path/to/project/subdir”))))

The .dir-locals.el is new in Emacs23 and is useful for other things, too. You should read the dir-locals docs to understand the format. The variable virtualenv-workon should just be a string the same as you'd give to the interactive function. The variable virtualenv-default-directory is useful when you want to have your python process rooted in a particular directory when it starts, so that no matter where you are in your project's hierarchy, if you launch a python shell. This method is recommended because it is more flexible and will allow multiple virtualenvs running at once in future versions.


virtualenv-workon will now modify Emacs' exec-path as well as the shell environment's PATH so that if you run shell-command or launch a command in an emacs subprocess it will use any commands it finds in your ~/.virtualenvs//bin directory.

virtualenv-deactivate will restore exec-path and PATH back to their original state prior to using the virtualenv-workon command.
