title: No module named 'channels'
body: <p>I am trying to install channels, following their tutorial(<a href="https://channels.readthedocs.io/en/latest/tutorial/part_1.html" rel="nofollow noreferrer">channels tutorial</a>) but when I try to run the server I get the error: No module named 'channels'.</p>
  
  <p>I have tried reinstalling it, moving the app to the top of the list of "INSTALLED_APPS" but it still does not work.</p>
  
  <p>I have installed python 3.7 and django 2.1.3</p>
