Answer by Bartłomiej Olszak-Mundzia for Django Import Error: No module named apps

I had exactly the same issue.In settings.py I printed the SYS path by:

  import sys  print(sys.path)

It turned out that main path to the project directory was not included, so I had to add it manually here.

  import sys  sys.path.append(<path to my main project dir>)
