I am on WSL2 in VS Code. Using Zsh on VS Code.
I am trying to install pythonnet though am getting two errors: ERROR: Failed building wheel for pythonnet error: option --single-version-externally-managed not recognized
This is from using pip install pythonnet==2.5.2
My versions are: Python 3.8.10 Wheel 0.37.0 Mono: 6.8.0.105 pycparser 2.20
I have searched high and low online though I can't find a solution - everything seems to point to updating wheel and installing mono - as you can see from the above version numbers, I have them installed. I am doing everything from within a virtual env.
Does anyone have any experience with this or know what to do to get past these errors?

You need a newer version of Mono. The one you have does not support C# 7.3 that Pythonnet build needs.
