Cannot start Celery Worker (Kombu.asynchronous.timer)

I followed the first steps with Celery (Django) and trying to run a heavy process in the background. I have RabbitMQ server installed. However, when I try, celery -A my_app worker -l info it throws the following error

File "<frozen importlib._bootstrap>", line 994, in _gcd_import
File "<frozen importlib._bootstrap>", line 971, in _find_and_load

from kombu.asynchronous.timer import Entry
ModuleNotFoundError: No module named 'kombu.asynchronous.timer'

I've searched a lot, but can't seem to get it working. Any help will be highly appreciated. Thank you!

Solution

  • I have the same problem, but solved it when reinstall celery with version 3.1.25

    pip uninstall celery && pip install celery==3.1.25

    Maybe because windows is not officially supported by celery 4， https://github.com/celery/celery/issues/3551
