title: Django: No module named apps
body: <p>The module <code>django.apps</code> cannot be found. It is a module normally included in Django, therefore I don't understand where this error comes from.</p>
  
  <p>This happens after installing djangorestframework and adding this line:</p>
  
  <pre><code>from rest_framework import routers, serializers, viewsets
  </code></pre>
  
  <p>The CLI output shows that Django version 1.6 is detected:</p>
  
  <pre><code>In [1]: from django.apps import apps
  ---------------------------------------------------------------------------
