GraphicsContextArray missing its __swig_setmethods__ attribute?

Question

After porting one of my Traits/UI/Chaco/Enable projects from Python2 to Python3, I'm getting the following error, which I'm having a hard time troubleshooting. I was hoping someone might have a suggestion for making forward progress.

Thanks!

My package versions:

$ conda list | grep 'traitsui\|traits\|chaco\|enable\|swig'

I recommend asking on the Enthought Tool Suite users group (https://groups.google.com/forum/#!forum/ets-users) — Jonathan March, Jul 08 '19 at 20:34
Sorry about that! Formerly, there was a link to request to join (to avoid spam). I don't know whether this current obstacle is a change from google or from the group owners. I'll investigate. — Jonathan March, Jul 09 '19 at 00:08

This was due to the SWIG version. For building the Enable package, SWIG v4 does not work; use v3.
