title: Problem with django installation [python]
body: <p>Last summer I wanted to learn to do web dev, so I installed Django 1.8, an unstable release. I installed it without pip. I recently decided to try again, but wanted to do work with the stable release, 1.7.1, and wanted to install with pip for simplicity.</p>
  
  <p>I read that in order to remove Django that was installed without pip, one must delete the entire <code>.egg</code> from <code>/Library/Python/2.7/site-packages/</code>, so I did this.</p>
  
  <p>Since then, I've been getting funny errors. When I issue 'pip install django', I get </p>
  
  <pre><code>bash-3.2$ pip install django

  <p>When I check the spurious directory, I find that /django doesn't exist.
  Issuing sudo will silence the errors, but I find that I still can't start a django project.</p>
  
  <p>Has anyone seen this before or have any idea how to fix this?</p>
