Hi :).
I wrote a simple widget for cmus <https://cmus.github.io/> , for my
personal usage (of course, if applicable, I want to share it). And it seems
to work, but when, according to Hacking on Qtile
<http://docs.qtile.org/en/latest/manual/hacking.html>, I try to pass the
appropriate test
nosetests --tests=test_widget
from a *virtualenv* environment, but I get nothing but errors. I installed
a bunch of packages with *pip*, but still I get certain errors caused by
other widgets. Specifically the *wlan* widget:
18:46 $ nosetests --tests=test_widget
E

I get that the *pythonwifi* module is needed, but, when can I find it?
If I search it with *pip*, don't get anything. It appears that the module
is given by *python-wifi*, but if I install that package with pip, I get
another error about that package:
18:47 $ nosetests --tests=test_widget

So, I'm not sure about it. What can I do about this? Anyone knows about a
package for pip that works for this? Am I doing something bad? Is this not
needed or what? Nobody is asking, so, it works? Ô_ó.
I use Python 3.4.3 in the virtualenv.
Thanks ;).
