Failure to start celeryd - Error : conflicting option string(s): --no-color

问题

I'm using django v1.7.0b4 and celery v3.1.1. Followed steps according to the django installation guide. But I'm stuck with the below error.

$ ./manage.py celeryd --help
Starting server in DEVELOPMENT Mode
Traceback (most recent call last):

optparse.OptionConflictError: option -C/--no-color: conflicting option string(s): --no-color

Is any one else facing the same issue ?

Edited :

Working good in django v1.6.5.

回答1:

You should use ./manage.py celery worker instead of ./manage.py celeryd

Looks like there is an bug when you use:

django==1.7b4
celery==3.1.11
django-celery==3.1.10

Few tips which will help you avoid this issues:

When you are starting playing with a project stay away from beta releases, use stable release.
Don't use deprecated methods: ./manage.py celeryd is old deprecated alias for ./manage celery worker

The incompatibility in django-celery was fixed two months ago: https://github.com/celery/django-celery/pull/320. If you are using virtualenv, then you could monkey-patch like this:

sed "s/\(= \['--app', '--loader', '--config'\)\]/\1, '--no-color']/"  -i \
    "$VIRTUAL_ENV/lib/python3.4/site-packages/djcelery/management/base.py"

Tested with Celery 3.1.13 and django-celery 3.1.10.
