Answer 1

I will add my answer to the same problem I had. This was unrelated from Django version, but in an old instance of my project I was providing my own Django copy and not installing from pip. Later I decided to use Pip installed Django.

When I pulled the changes on the server, my repo's copy of Django files were deleted but not the .pyc files. manage.py would still import the old .pyc files making the imports break half way and the error was the same "Unknown command: runserver".

Naturally, fully deleting the folder with the .pyc files fixed the problem.
