macropy.activate fails in Python 3.10.2

[danielshub]

I am unable to use macropy.activate from version 1.1.0b2 in Python 3.10.2 on Arch Linux. When running import macropy.activate I expected Python to cleanly import the package, but instead it gives an error related to lineno.

$ python

I'm running into the same error here, which prevents Psychopy from running. I don't know how to debug this...

[danielshub]

@DestyNova I got the problem via PsychoPy/javascripthon also:
https://discourse.psychopy.org/t/what-is-the-state-of-python-3-10-support/27303
https://discourse.psychopy.org/t/psychopy-2021-2-3-1-fails-to-start/27067

The solution for PsychoPy/javascripthon is to use the unreleased version of javascripthon that does not depend on macopy (https://github.com/metapensiero/metapensiero.pj/blob/master/CHANGES.rst)

Thanks @danielshub -- I was falling down the rabbit hole of debugging Macropy but this sounds like a better solution 👍

I've opened #108 which addresses this problem.
