title: zsh: command not found: django-admin when starting a django project
body: <p>I use Ubuntu 15.10 and zsh (don't know if it can help)<br>
  So I try to install django:</p>
  
  <pre><code>pip install django
  Downloading/unpacking django
    Downloading Django-1.9.5-py2.py3-none-any.whl (6.6MB): 6.6MB downloaded
  Installing collected packages: django
  Successfully installed django
  Cleaning up...
  </code></pre>
  
  <p>Everything works fine. When I do <code>pip freeze</code> I can see django is installed.</p>
  
  <p>then:
  <code>django-admin startproject mysite</code></p>
  
  <p>But I got this issue:<br>
  <code>zsh: command not found: django-admin</code></p>
