  <pre><code>ImportError: No module named 'app.settings.ci'; 'app.settings' is not a package.

  <p>I want to install CircleCI 2.0 into Django application. The traceback says:</p>

  <p>I run the command <code>python manage.py makemigrations --settings app.settings.ci</code> when the error happens. I think this command is necessary to install  CircleCI 2.0, but is it wrong? How can I fix this? What is wrong with my code?</p>
  
  <p>In settings.py I wrote</p>
