Python Mode console won't display anything

Created by: tabreturn

Description

I'm logging this issue here in response to @benfry's request: https://github.com/jdf/processing.py/issues/390#issuecomment-1013791048

The Processing 4 PDE isn't displaying any errors/warnings/print lines in the console using Python Mode --

Expected Behavior / Current Behavior

Errors/warnings/print lines should display in the console in Python Mode, but they don't.

Steps to Reproduce / Your Environment

I'm using a version of Processing.py that I built for 4.0a4: https://github.com/tabreturn/processing.py-for-processing-4

I cannot build with the 4.0b3 source, but possibly because I've forgotten how to do it properly. Perhaps somebody could provide advice on how to build Python Mode for 4.0b3; then, I can update the build instructions in the Processing.py repo?

System Info

• Processing version: 4.0a4
• Operating System and OS version: not-applicable I think (affects Win and Linux)

Start by reproducing the missing errors, warnings, and print lines in the Processing 4 PDE with Python Mode, using the reported 4.0a4 environment. Then trace the Python Mode build and PDE console integration; done means those messages appear in the console, with build guidance clarified for 4.0b3 if relevant.
