Installing error: cannot import "ensure_str" from "six" #58

Thanks for reporting. Haven't seen this one before. What environment are you running it in: are you inside a virtualenv? What does "pip list" show? |
The environment for "six" import error: I just tried intall witwidget within a virtual env.

Hi, I encounter an error while executing
jupyter nbextension install --py --symlink --sys-prefix witwidget

But I can import ensure_str within my python2 and python3, where could it go wrong?
Thanks a lot.
