Django No module named 'django.db.migrations.migration'

Question

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):

I have no idea what I did wrong.

Answer 1

Your Django installation seems corrupted. You can reinstall with:

pip3 uninstall Django
pip3 install Django

Usually this happens if you installed Django in your regular operating system's python installation and then later installed a virtualenv copy and tried to run the django server. You need to reinstall Django in your virtualenv, after removing it first if it already exists.

Answer 2

Assuming you are running in the virtual environment, you might have actually deleted the files under /django/db/migrations/ as well. So the error is obvious here. You would need to reinstall django to get the files back for successful migration.

To do this, check the django version

python -m django --version

Then install the same version using following command

pip install --upgrade --force-reinstall  Django==3.2.2
