In order to solve this issue, I had to install urwid manually before installing the projects requirements : pip install urwid Maybe we can find a way to solve this problem?

I'm using pip version 19.1.1 and python version 3.7.3

HI,

I've experienced this myself also when I wrote this code. The requirements.txt file seems fine... and so I fixed it also by a manual install. It bit googling gives the impression that it is a more common issue related to urwidtrees.

Currently I have no plans to look further into this because it has an easy work-around
