ImportError: cannot import name parse_lookup

I believe the error is due to the django-tagging package missing. Even so, Django 1.4 was just released two weeks ago and Graphite hasn't yet made the changes yet to be compatible with it (see https://bugs.launchpad.net/graphite/+bug/963684) so I'd suggest starting with Django 1.3 as you'll run into other issues otherwise.

I have django-tagging present, and I reverted to 1.3 but I still have this problem:
python manage.py syncdb

ImportError: cannot import name parse_lookup

I also reverted from Django 1.4.3 to 1.3.5 and get the same error:

...
from django.db.models.query import QuerySet, parse_lookup
ImportError: cannot import name parse_lookup

Do you have django-tagging installed?

You can see what python packages you have installed with "pip freeze". You
should see something like:

...
django-tagging==0.3.1
...

Hi rowan, I do have tagging installed:

# pip freeze |grep tagging
tagging==0.2.1

# pip install tagging --upgrade
Requirement already up-to-date: tagging in /usr/lib/python2.6/site-packages
