title: How to solve the ImportError: cannot import name simplejson in Django
body: <p>I'm trying to build a realtime chat app in Django(1.7.1). It seems that I needed to install Redis and ishout.js. So I installed them by following the instructions. </p>
  
  <p>After making the project in Django, I put 'drealtime' under the INSTALLED_APPS, and put:</p>
  
  <pre><code>'drealtime.middleware.iShoutCookieMiddleware' 
  </code></pre>
  
  <p>right above :</p>
  
  <pre><code>'django.contrib.sessions.middleware.SessionMiddleware' 
  </code></pre>
  
  <p>under the <code>MIDDLEWARE_CLASSES</code> as it was saying. And I put the command like </p>
  
  <pre><code>python manage.py startapp example
  </code></pre>
  
  <p>but still I have this import error message: </p>
  
  <pre><code>Traceback (most recent call last):

      from django.utils import simplejson as json
  </code></pre>
  
  <p>After I searched through the Django official site, I found simplejson is no longer used and removed from new Django. I don't know why this is happening. 
  Please give any feedback on this issue and possible remedy to tackle this issue.</p>
