title: ImportError: No module named django.core.management when using manage.py
body: <p>I'm trying to run <code>python manage.py runserver</code> on a Django application I have and I get this error:</p>
  
  <pre><code>Traceback (most recent call last):
  File "manage.py", line 8, in &lt;module&gt;
   from django.core.management import execute_from_command_line
  ImportError: No module named django.core.management
  </code></pre>
  
  <p>Here is the output of <code>pip freeze | grep -i django</code> to show I do in fact have Django installed:</p>
  
  <pre><code>Django==1.6.5
  django-cached-authentication-middleware==0.2.0
  django-cors-headers==1.1.0
  django-htmlmin==0.7.0
  django-static-precompiler==0.9
  djangorestframework==2.3.14
  </code></pre>
  
  <p>Also, trying to run <code>/usr/local/bin/python2.7 manage.py runserver</code> yields the same error.</p>
