I\'m using virtualenv and the virtualenvwrapper. I can switch between virtualenv\'s just fine using the workon command.
me@mymachine:~$ workon
You can use virtualenvwrapper in order to ease the way you work with virtualenv.
Installing virtualenvwrapper:
pip install virtualenvwrapper
If you are using a standard shell, open your ~/.bashrc or ~/.zshrc if you use Oh My Zsh. Add these two lines:
export WORKON_HOME=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh
To activate an existing virtualenv, use command workon:
$ workon myenv
(myenv)$
In order to deactivate your virtualenv:
(myenv)$ deactivate
Here is my tutorial, step by step on how to install virtualenv and virtualenvwrapper.
