missing urwid dependency?

[dpinol]

In OSX, with python 3.6 and pip 9.0.1, it failed to automatically install the urwid dependency.

sudo pip3 install sen

After manually installing urwid, it worked fine

This issue comes from urwidtrees, what you are seeing is combination of these issues: pazz/urwidtrees#28 pazz/urwidtrees#24 pazz/urwidtrees#35

Unfortunately I wasn't able to resolve this (so $ pip3 install sen works) -- the solution is to install urwid explicitly before installing sen. I proposed patch to document this, can you take a look? #128

[dpinol]

hi, thanks! I guess you meant #129 instead of #128 in your last comment

[TomasTomecek]

Yes, #129, my bad.

[dpinol]

dealt by #129. Thank you @TomasTomecek

Thanks. pip3 install urwid is a workaround.
