ERROR: virtualenvwrapper could not find virtualenv in your path

I'm trying to create a virtualenv with virtualenvwrapper, but when I use mkvirtualenv I get the following :

ERROR: virtualenvwrapper could not find virtualenv in your path

I assumed it was a PYTHONPATH problem. But if I do a pip show virtualenv I get the following :

And here is my PYTHONPATH :

/nfs/zfs-student-3/users/2013_paris/vmonteco/Library/Python/2.7/bin:/nfs/zfs-student-3/users/2013_paris/vmonteco/Library/Python/2.7/bin:/nfs/zfs-student-3/users/2013_paris/vmonteco/Library/Python/2.7/lib/python/site-packages:/Volumes/Data/nfs/zfs-student-3/users/2013_paris/vmonteco/Library/Python/2.7/lib/python/site-packages:~/.brew/Cellar

It contains the directory containing virtualenv!

(i-e : /Volumes/Data/nfs/zfs-student-3/users/2013_paris/vmonteco/Library/Python/2.7/lib/python/site-packages )

My ~/.zshrc contains :

export WORKON_HOME=~/Envs
export PROJECT_HOME=$HOME/Devel
source $HOME"/Library/Python/2.7/bin/virtualenvwrapper.sh"

EDIT : virtualenvwrapper.sh is written in bash, perhaps should I check my PATH instead of my PYTHONPATH ?

So, what could the problem be? How could I fix it?

Thank you in advance for your help.

Solution

  • I finally found out what the problem was :

    virtualenvwrapper.sh is written in BASH and not in Python. So virtualenv is called from a shell (zsh). I didn't have to bother about my PYTHONPATH, but about my PATH (I was already able to import virtualenv from my python shell anyway).

    I just added the correct directory to my PATH and everything worked fine (the directory containing the virtualenv executable, i-e /Volumes/Data/nfs/zfs-student-3/users/2013_paris/vmonteco/Library/Python/2.7/lib/python/site-packages which isn't included in my PATH by default despite being the directory virtualenv and other pip-installed tools was in).
