GitHub workflows doesn’t find a module

I’m trying to configure tests in the GitHub workflows for my FastAPI application. My alembic.ini -file is located in app folder. The alembic ´env.py´ is located in app/alembic.

This is how I try to run migrations:

- name: Migrate
        env:
          DB_USER: postgres
          DB_HOST: localhost
          DB_PASSWORD: postgres
        working-directory: app/
        run: |
          alembic upgrade head

GitHub finds my alembic.ini file but the problem is, in app/alembic/env.py I have an import from app.core.config and that gives me an error:

File "alembic/env.py", line 13, in <module>
    from app.core.config import settings  # noqa: E402
ModuleNotFoundError: No module named 'app.core'

I’ve tried setting the directory in the env.py like this:

from os.path import abspath, dirname

sys.path.insert(0, dirname(dirname(dirname(abspath(__file__)))))

Without this, I get an error ModuleNotFoundError: No module named 'app'.
Any help would be appreciated.

Method 1

The solution to my problem was to remove the line sys.path.insert(0, dirname(dirname(dirname(abspath(__file__))))) and run the migrations like this: PYTHONPATH=. alembic upgrade head.
