  <p>Not only do I have celery, but it's also using python 2.7 from outside the virtenv. When I type which python while I'm in or out of the environment they both come from the same location which according to hitchhikers guide to python they should be seperate. What's going on? shouldn't it be using the python from within ythe virtual env?</p>
  
  <p>then when I tried to pip install django-celery I got the following</p>
