Description Randy Barlow 2013-08-30 02:05:18 UTC
I installed python-celery-2.2.8-1.el6.noarch today, and I attempted to start a Celery worker by running celeryd. celeryd generates a Python traceback, because it has a runtime requirement on python-dateutil >= 1.5.0. Unfortunately, only python-dateutil-1.4.1-6.el6.noarch is available on my system, as provided by Red Hat. EPEL does not seem to provide the necessary newer version of python-dateutil.

The symptom is best demonstrated by simply trying to start celeryd:

$ celeryd
Traceback (most recent call last):
  File "/usr/bin/celeryd", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python2.6/site-packages/", line 2659, in <module>
    parse_requirements(__requires__), Environment()
  File "/usr/lib/python2.6/site-packages/", line 546, in resolve
    raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: python-dateutil>=1.5.0,<2.0.0

In my opinion, the best solution is to provide a newer version of python-dateutil that will satisfy this dependency, and make the RPM for python-celery depend on that version.

Thanks, and let me know if you need any further information!

could you please try the following:
yum install python-dateutil15
and retry?
It looks like there is a newer version available, but not marked as requirement:
If that works, I'll fix the package.

Thanks, that does seem to work!
