[Python] Django No module named 'django.db.migrations.migration'

I had a custom user model in my project. I wanted to delete it and return default user model by deleting all tables in my database and deleting migrations. After this, I tried to run python manage.py makemigrations command but it writes:

Traceback (most recent call last):
