Can’t open word-o-mat in Glyphs 3

I’m trying to get word-o-mat to open in Glyphs3, but it gives me this error:

This plugin needs the module to be installed for python 2.7

However, I have all suggested modules installed, and I don’t see an option for 2.7 (and wouldn’t that conflict with Python 3, anyway?):

I’ve uninstalled and reinstalled word-o-mat from the Plugins Manager.

Is there something I’m missing? Or do folks use something a different plugin for word-o-mat functionality these days?

(I’ll be teaching a workshop this week, so I’m hoping to show the students how to test in-progress glyph sets, and I love word-o-mat for that.)

Thanks for any pointers!


  • Glyphs 3.2 (3182)
  • MacOS 13.0 (22A380) — on an Intel Mac, if that is relavant

What python version do you have selected in Preference > Adons > Python version?

And can you reinstall the other modules, too?

Thank you, Georg — word-o-mat works again, after removing and re-installing all four of the Python modules!

I had (and still have) the Python version 3.9.1 (Glyphs) selected:
