Issue with KeyError: 'unix_user'

[Maverick-Oh]

• pyHalo version:
• Python version: 3.10
• Operating System: macOS Monterey (Version 12.6)

Description

I tried to install pyHalo on my intel Mac mini. It had an error. It seems to have come from MacOS's own setuptool issue. I was able to solve it with some other resources, but I thought it can be good to document it.

What I Did

$ python setup.py develop --user
running develop

I was able to solve this by

pip install setuptools --upgrade

I also followed the direction of this link too, but it didn't help. It might have helped together with setuptools upgrading.
