[FIXED] "django.db.utils.ProgrammingError: relation "auth_user" does not exist" Django V2.0

Issue

I've recently upgraded Django to V2.0 and I'm unable to make migrations due to the following error:

django.db.utils.ProgrammingError: relation "auth_user" does not exist

I know a similar bug existed in V1.8 which I fixed by migrating the model which others depend on, i.e. auth_user and then the rest:

python manage.py migrate auth
python manage.py migrate

When I try to migrate 'auth' I encounter the same error. Has anybody encountered/found a solution to this?

Solution

I encountered the same error.
At last I found the root cause was the database.
There may be some auth info in the database already.
Editing setting.py and using another new database will solve this problem.
