Unable to import Celery

[rrfirstwork]

Bug report

Unable to run mypy with django-stubs, even with ignore_missing_imports=true.
Celery is set up in the app2/ init.py file:

from __future__ import absolute_import, unicode_literals
# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from app2.celery_script import app as celery_app


__all__ = ("celery_app",)

What's wrong

Should be able to run mypy checks without crashing.

How is that should be

System information

• OS:
• python version: 3.9.6
• django version: 4.2.13
• mypy version: 1.7.1
• django-stubs version: 4.2.7
• django-stubs-ext version: 4.2.7

This is a duplicate of #329

The plugin uses the Django runtime, so if the runtime crashes, the plugin/mypy crashes. It's also mentioned in the README section "mypy crashes when I run it with this plugin installed"

To fix it you need to make sure the environment you're running mypy in has celery installed and available.

@flaeppe the env does has celery installed if i comment out mypy the application works just fine. also opening the python terminal in the env and running celery imports also work fine

[flaeppe]

Looks like, from the traceback, that mypy runs via pre-commit. Does the pre-commit environment have celery installed and available?

[rrfirstwork]

it's there in requirements.txt do i need to do anything else?

[rrfirstwork]

@flaeppe i have added

- repo: local
  hooks:
  - id: install-dependencies
    name: Install Dependencies
    entry: ./install_dependencies.sh
    language: script
    types: [python]

in the precommit config . It doesn't work still
