ModuleNotFoundError: No module named 'django.config' using celery and rabbitmq

Question

I'm getting this error after running the following command:

C:\Users\callu\project_name>celery -A project_name worker -l info

I'm wondering if it has something to do with the fact that I've not created my django project in a virtual environment but I can't find anything on the issue. If it was due to it being outside a virtual environment I'm not sure how I'd get around it without restarting the project in one (is it easy to move to a venv in PyCharm?)

I run my django server and my above celery command here:

C:\Users\callu\project_name>

I run start my RabbitMQ server in another location (not venv) but don't think that's the issue

ModuleNotFoundError: No module named 'django.config'

Answer 1

It sounds like you have somewhere (in your app/celery.py if using the standard layout) a line that looks like:

app.config_from_object('django.config:settings', namespace='CELERY')

where app is your Celery app object.

But what you need is:

app.config_from_object('django.conf:settings', namespace='CELERY')

Note: you the django config module is django.conf not django.config.
