py38-gobject3 @3.28.3_0 Can't import Gtk

[InvisibleFunction]

I'm running Mac OS 10.14.6 with Xcode Version 11.3.1 (11C504).

I was having trouble running a python app but I was able to reproduce the problem by following a simple Python GTK tutorial. I'm following the steps from ​https://python-gtk-3-tutorial.readthedocs.io/en/latest/introduction.html

I've got these installed:

[me@laptop ~]$ port echo installed | grep -i -e "py38-gobject" -e "^gtk3" -e "^python38"
gtk3                           @3.24.18_0+x11
py38-gobject3                  @3.28.3_0
python38                       @3.8.2_0

and trying to run this causes a Traceback (which I'll attach):

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

There's an ​upstream bug report but it's also from a MacPorts user so it's not clear whether this is a MacPorts-specific problem or an upstream one.

We're several versions behind on py-gobject3. Maybe updating would help?

This bug is the reason why I can't use python 3.8 for MyPaint 2.

Updating py-gobject3 has cured this problem for me so I'll call it fixed.
