Installation issues with virtualenvwrapper on Debian and Ubuntu

When I do:

pip install -r requirements.txt

and install ipython[notebook]

I have this problem when I open a terminal in ubuntu and Debian.

Traceback (most recent call last):

"__main__", fname, loader, pkg_name)

virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is
set properly.

This error happen twice in a Deban virtual machine and in an Ubuntu
