TypeError: 'NoneType' object is not iterable

When trying to convert the api for Cozmo, the following error occured:

Converting intersphinx docs from "cozmo-api" to "/Users/andy/Library/Application Support/doc2dash/DocSets/cozmo-api.docset".

Given the last 6 lines, it looks like your Python or click installation is broken. Try installing doc2dash into a fresh virtualenv. The paths in your traceback tell me that you installed it globally. Never install anything into your global site-packages. You may want to try pipsi as recommended in the installation guide.

Ha, the one time I don't install cli tools in pipsi...

However, after installing it in pipsi, I'm still getting the same error. I made the path to python explicit to be sure:
