Getting error while runing celery commad:

Celery command :

  File "/usr/bin/celery", line 9, in <module>

    self.app = self.find_app(app)

    from django.conf import settings  # noqa
ImportError: No module named django.conf

Then I identified celery library was thers, So I installed celery with pip install celery and got the following error:

[ask]

The first error means Django was not installed, the second error means you are using the API of Celery 4.0 but running Celery 3.1

The namespace argument to config_from_object was introduced to the development version, it does not exist in Celery 3.1.

You should use the documentation from http://docs.celeryproject.org/en/latest for the stable release,
and the git branch https://github.com/celery/celery/tree/3.1 for the 3.1 series.
