[BUG] Tracebacks don't seem to work in JupyterLab

Read the docs

There doesn’t seem to be an indicator that this wouldn’t work.

Describe the bug

The traceback handler doesn’t seem to do anything in IPython or xeus-python in Jupyter.

To Reproduce

import rich.traceback
rich.traceback.install(show_locals=True)

1 / 0

I feel like this might have worked in the recent past? At least I know I tried it and I thought I was in Jupyter, since I like to play around there. But it’s not working now, certainly. It works in the regular REPL.

Platform macOS, JupyterLab 3, rich 9.8.0

@henryiii This work now. Thanks to @nathanrpage97

You might be able to get Rich to work in this case using monkeypatching with just a two lines of code (redefinint shell.InteractiveShell.showtraceback and shell.InteractiveShell.showsyntaxerror. See https://github.com/aroberge/friendly-traceback/blob/master/friendly_traceback/ipython.py for an example.
