Steps to reproduce

virtualenv -p python2.7 ~/venv
~/venv/bin/python ./setup.py install
~/venv/bin/pulseaudio-dlna 

Result

Traceback (most recent call last):
  File "/home/jdoe/venv/pulseaudio-dlna/bin/pulseaudio-dlna", line 11, in <module>
    load_entry_point('pulseaudio-dlna==0.5.2', 'console_scripts', 'pulseaudio-dlna')()

ImportError: No module named gi.repository

Possible Cause

I suspect this is because #253 didn't add PyGObject as a dependent pypi package

Partial Workaround

In trying to workaround this, I also found that in order to install PyGObject on Ubuntu 18.04 I had to do the following in response to errors during ~/venv/bin/pip install PyGObject

Cairo

Error : No package 'cairo' found

Solution : sudo apt install libcairo2-dev

gobject-introspection-1.0

Error : Package gobject-introspection-1.0 was not found in the pkg-config search path

Solution : sudo apt install libgirepository1.0-dev
