Error: Missing xlib about key-mon HOT 5 CLOSED

Sorry,
the full error is this..

Traceback (most recent call last):
  File "/usr/bin/key-mon", line 2, in <module>
    import keymon.key_mon as km
  File "/usr/lib/python3.4/site-packages/keymon/key_mon.py", line 38
    print 'Error: Missing xlib, run sudo apt-get install python-xlib'

I am not familiar with Arch Linux, but I think the default Python is Python 3 
on Arch and the traceback seems to confirm that.

I am guessing that you didn't install key-mon through Arch's key-mon package, 
or the PKGBUILD will make sure it runs with python2.

You should be able to run `python2 /usr/bin/key-mon` if you really don't want 
to install the distribution package.

Thank you so much.
I feel like an idiot but I actually searched for the arch package and didn't 
find it before which is why I installed from source. I think I missed the dash 
in the package name when I did the search.

pip uninstall keymon and aur install key-mon fixed everything.
Many thanks!

You'll need to run:
sudo apt-get install python-xlib

as the error message notes.
