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'

Where is django.config from? (And in case you missed it, that's not the original exception.) — aaron

Ah I didn't realise that wasn't the first exception, sadly that exception isn't very descriptive, an error with a dictionary in the cached_property.py file? django.cofig is in my celery.py file here app.config_from_object('django.config:settings', namespace='CELERY'). At least that's where I think it's coming from. — Callum

Yes! So simple, can't believe I kept missing that, thanks for the help — Callum

Could you reproduce the exception with cached_property? What's Scripts\celery.exe\__main__.py", line 7? — aaron

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.
