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):
  File "manage.py", line 15, in <module>

    from .migration import Migration, swappable_dependency  # NOQA
ModuleNotFoundError: No module named 'django.db.migrations.migration'

I have no idea what I did wrong.

I had the same problem. Tried to reinstall django and my whole .venv but I still got the same error.

What fixed it for me was to run manage.py makemigrations myapp --empty to apply an initial migration and after that makemigrations and migrate.

In this case, its best to reset your virtual environment and reinstall dependencies, you can follow these steps or follow the project :

python -m venv .venv
source .venv/bin/activate  # or source .venv/bin/activate.fish
pip install -r requirements.txt  # or poetry install

Without thinking I copy-pasted and run this oneliner in the root directory.

find . -path "*/migrations/*.py" -not -name "__init__.py" -delete

Well, I had Django installed within the venv, and - surprise surprise - there's a migrations package in the Django source code. After reinstall everything works fine.

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

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.
