Makemigration Causing Error "TypeError: Expected Str, Bytes Or Os.PathLike Object, Not NoneType"

Running makemigration command inside docker container caused this error, can anyone please help me figure out what the problem is ? python3.7 manage.py makemigrations Traceback (m

Solution 1:

Please check absence of your_app/migrations/__init__.py

If it's not present django could be throw this exception and the solition in this case

-> add __init__.py the execute python manage.py makemigrations again

Solution 2:

You are using an old version of django.

from importlib import import_module
import_module('yourapp.migrations')

import_module behaviour has changed in python 3.6 (or 3.7, I don't remember).

Either bump your version of django or use python < 3.7
