django.template.library.InvalidTemplateLibrary

[SummerSeaSun]

This error is reported when trying to request the url of a simple view:

InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'django_nvd3.templatetags.nvd3_tags': cannot import name Environment

django.template.library.InvalidTemplateLibrary

I've installed django-nvd3, added to project settings in the installed_app and copied demo_scatterchart(request) in the view.
I've looked in nvd3_tags.py but nothing like Environment seems to be called for import.

Thanks in advance, BR

Same problem here. Did you find any clue?

Update : Managed to get it working deleting the whole virtual environment and reinstalling all python packets from scratch.
