1899940 - mach mochitest fails due to no distutils in python 3.12

Status: RESOLVED DUPLICATE of bug 1888570

(Testing :: Mochitest, defect)

Description

[Timothy Nikkel (:tnikkel)]

According to this page https://docs.python.org/3.10/library/distutils.html "distutils is deprecated with removal planned for Python 3.12". My python3 command is version 3.12.3

./mach mochitest toolkit/components/extensions/test/mochitest/test_ext_browserAction_openPopup_incognito_window.html
Error running mach:

mach mochitest toolkit/components/extensions/test/mochitest/test_ext_browserAction_openPopup_incognito_window.html

The error occurred in mach itself. This is likely a bug in mach itself or a
fundamental problem with a loaded module.

You can invoke ./mach busted to check if this issue is already on file. If it
isn't, please use ./mach busted file general to report it. If ./mach busted is
misbehaving, you can also inspect the dependencies of bug 1543241.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:

ModuleNotFoundError: No module named 'distutils'

I think I fixed this with something like brew install python-setuptools.
