Exception Value: Invalid template library specified. ImportError raised when trying to load 'django.templatetags.future': cannot import name 'RemovedInDjango110Warning'

Anyone? :)

Last time i saw RemovedInDjango110Warning it was in 1.9 and it was related to some = comparision in template, which was removed by me before update.

From the comments:

django/templatetags/future.py was deprecated and removed at version 1.10.

Uninstalling Django, removed django/ folder before re-installation will solve this issue.
