I have a Django project that uses Celery for running asynchronous tasks. I'm doing my development on a Windows XP machine.
Starting my Django server (python manage.py runserver 80) works fine, but attempting to start the Celery Daemon (python manage.py celeryd start) fails with the following error:
ImportError: Could not import settings 'src.settings' (Is it on sys.path? Does it have syntax errors?): No module named src.settings
sys.path includes 'C:\development\SpaceCorps\src', so I'm not sure why it can't find this module.
Here's the full output from starting the daemon:
C:\development\SpaceCorps\src>python manage.py celeryd start

Apparently this is a problem with running Celery on Windows. Using the --settings argument ala python manage.py celeryd start --settings=settings did the trick.
sys.path must include 'C:\development\SpaceCorps' not 'C:\development\SpaceCorps\src', because he is looking for src.settings, not just settings.
