title: Different versions of Django are imported when Run and Debug in Pycharm
body: <p>I want to upgrade a Django project from Django 1.2.5 to Django 1.11 on a server, and I added a remote project interpreter in Pycharm on my local machine. In order to switch between Django 1.2.5 and Django 1.11 conveniently, I downloaded the source code of Django 1.11 and added it to <code>sys.path</code> in <code>manage.py</code> by</p>
  
  <pre><code>sys.path.insert(0, 'Django_1_11')
  </code></pre>
  
  <p>where <code>Django_1_11</code> is the folder of source code. When I Run my project, it works and Django 1.11 is imported. But when I Debug my project, Django 1.2.5 is imported even if <code>Django_1_11</code> is in the <code>sys.path</code>. How can I import Django 1.11 in the Debug mode?</p>
