Does "gi" exist for python 2? How to get it?

Build pygobject3 with python2. pygobject is for Gtk2.

Python2 goes out of support at the end of *this year*. It's way past time that you covert your app to 
python3. It's not hard, most apps can be converted in a day or two.

Thanks John for the clarification, I thought pygobject3 was for Python 3 :-(
I made this misunderstanding because I got this error with Python 2:

*** Building pygobject3 *** [4/4]
python setup.py build
Traceback (most recent call last):
File "setup.py", line 29, in <module>
import pkg_resources
ImportError: No module named pkg_resources

What is going on?

It's entirely possible that python2 support has been pulled from pygobject3. If that's the case then 
you'll need to roll back to an older version of gtk-osx, modify and use local modulesets with an earlier 
version of pygobject3, or update your application to python3.

README.rst says it supports python2, so I Googled pkg_resources. It's part of python and when I run 
/usr/bin/python and say import pkg_resources it happily does so. Seems that you've broken your python 
installation.

Hello John,

When I used Python installed by macOS it is ok:
$ which python
/usr/bin/python
$ python
Python 2.7.10 (default, Oct  6 2017, 22:29:07) 
[GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.31)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
import pkg_resources
^D

But not with Python installed formerly with jhbuild:
$ PATH=$HOME/.local/bin:$PATH
$ jhbuild shell
Prefix: /usr/local/xnadalib-2018
Entered jhbuild shell, type 'exit' to return.
[JH]$ which python
/usr/local/xnadalib-2018/bin/python
[JH]$ python
Python 2.7.14 (default, Sep 13 2018, 10:35:57) 
[GCC 4.2.1 Compatible Apple LLVM 9.1.0 (clang-902.0.39.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
import pkg_resources
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named pkg_resources


So I uninstalled python and installed it again.
I have now a different error:
*** Building pygobject3 *** [4/4]
python setup.py build
Traceback (most recent call last):
File "setup.py", line 30, in <module>
  from setuptools import setup
ImportError: No module named setuptools

Pascal,

Drop to the shell and run
python -m ensurepip

to install setuptools and pip.

Control-d to return and rerun the build

AhAh thanks John, pip, setuptools and ... pkg_resources come into site-package folder :-)

And ... "gi" comes with pygobject3 :-)

On the side of my app (well the app I try to port on macOS) is running with lots of gtk-warning but it is 
running.

By the way, how can I help with your new buid system from https://github.com/jralls/gtk-osx-build/tree/pipenv?

Thanks again, Pascal.
