Redshift: Unable to run redshift-gtk

[SethGower]

Describe the bug
I am unable to run redshift-gtk on my new install, but can on my laptop (which has been installed for a while). I am getting the error

Traceback (most recent call last):
  File "/usr/bin/redshift-gtk", line 26, in <module>
    from redshift_gtk.statusicon import run
  File "/usr/lib/python3.7/site-packages/redshift_gtk/statusicon.py", line 31, in <module>
    gi.require_version('Gtk', '3.0')
AttributeError: module 'gi' has no attribute 'require_version'

• [x] [I have checked the FAQ](https://github.com/jonls/redshift/blob/master/README.md#faq) and my issue is not mention there.

To Reproduce
I honestly don't know. I just run redshift-gtk and it fails. redshift works perfectly.

Expected behavior
redshift to run but with a status icon

I feel really stupid, but I figured out the problem. I didn't have python-gobject installed, I only had python2-gobject and python2-gobject2 installed. Once installing python-gobject, redshift-gtk worked
