I installed gnu health on arch linux. The installation went fine. Even installation of gnuhealth-client went uneventful, but when I run gnuhealth-client it gives me the following error.
Traceback (most recent call last):
File "/usr/bin/gnuhealth-client", line 46, in <module>
from tryton import client
File "/usr/lib/python3.6/site-packages/tryton/client.py", line 108, in <module>
ModuleNotFoundError: No module named 'pygtk'
I installed the gnuhealth-client by pip
