I have install GTK+ 3 and Python with:

Then PyObject with:

But I've the error: "ImportError: No module named gi"

Where is it wrong?

pygobject needs gobject-introspection. Build meta-gtk-osx-core-gtk3 instead of just gtk+-3.0.
Also you need python3 rather than python nowadays.

Hello John,

Sorry, my wording was incorrect.
$ jhbuild build pygobject
is built without any error.
But I've got "ImportError ... gi" when running my app.

Well, I built python3 and pygobject3 but I've got another error:
$ jhbuild build python3
$ jhbuild build pygobject3
*** Building pygobject3 *** [4/4]
python build
Traceback (most recent call last):
File "", line 29, in <module>
  import pkg_resources
ImportError: No module named pkg_resources

Note that it calls python, not python3. Since you have built both (and maybe even if you hadn't) you need 
to link $PREFIX/bin/python3 to $PREFIX/bin/python, replacing the python2 link.

Thanks John for the tip, I should have guess it on my own ;-)

Now "jhbuild build pygobject3" is ok and I get "gi":
$ jhbuild shell
Prefix: /usr/local/xnadalib-2018
Entered jhbuild shell, type 'exit' to return.

__main__:1: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk',

But my app seems to expect python 2:
    print 'PYTHON_VERSION=%s' % get_config_var("VERSION")
SyntaxError: invalid syntax

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

Thanks, Pascal.
