AttributeError: 'module' object has no attribute 'getmro'

Question

I try to start a python app and after many problems with dependencies I got into another problem. After googling for a few hours I turned to my fav site for answers

python manage.py runserver

gives:

I searched but I could not find a file names inspect.py in the project. Any idea is much appreciated. Thanks!

EDIT:

mdfind inspect.pyc 

gives

/Library/Python/2.7/site-packages/django/utils/inspect.pyc

/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/test/test_inspect.pyc

EDIT:

I removed python 2.6 but that does not save the problem.

Answer 1

You require django-inspect.
Install it using pip install django-inspect

Answer 2

I managed to solve this error by removing all the project files, reinstalling python and cloning the project once again. Thanks!
