TypeError: __init__() takes 1 positional argument but 2 were given

New to django-pipeline and trying to get it up by following the guide at readthedocs.io and using a vanilla Django 1.10.4 installation, but I’m getting an error “TypeError: init() takes 1 positional argument but 2 were given” and can’t figure out what’s causing it.

Python 3.5.2 MacOS 10.12.1

Full stacktrace:

In your urls.py:

Maybe you are missing .as_view()

change it to: view.(name of your apiview class).as_view()
