And the pip command that is found and run will use it's own settings 
regarding where to install packages, even if you activated a virtualenv. 
For example, you can't use /usr/bin/pip to install something in a 
virtualenv. To install something in a virtualenv, you need to use the 
pip in that virtualenv (either by first activating that venv, or by 
running something like venv/bin/pip, or venv). (Of course to do that pip 
needs to be installed in that venv. That might or might not be the case 
depending on how the venv was created.)

I kinda get the feeling that something like that is going on here.
