Following on from my last question Error: No module named psycopg2.extensions, I have updated my mac OS to Mountain Lion and installed Xcode. I have also installed psycopg2
If you're working on a Django project, the root of your project(ROOT_URLCONF= variable) isn't defined in your settings.py file, or at least it isn't defined properly.
If you don't have a settings.py file, this block of code should fix the issue:
from django.conf import settings
settings.configure(
# ...
ROOT_URLCONF=__name__,
# ...
),
)
What that does is specify the root of your project runserver knows where to find your project.
If do have a settings.py file, then find that variable and add __name__ to it.
