I'm trying to install the package pyminifier at the command prompt, this happens:
C:\Users\[my name]\Downloads\JKLMBombpartyHelper-master\JKLMBombpartyHelper-master>python -m pip install pyminifier
Collecting pyminifier

Python 3.X support requires the 2to3 tool.
It normally comes with Python 3.X but (apparenty) not on your distribution.
Please find out what package you need to get 2to3and install it.

note: This error originates from a subprocess, and is likely not a problem with pip.

However, if I attempt to install 2to3 using pip install 2to3, I find that it is already installed:
Requirement already satisfied: 2to3 in c:\users\[my name]\appdata\roaming\python\python310\site-packages (1.0)
What is wrong, and how do I fix it?
My guess is that it fails because pip tries to build a wheel of pyminifier in an isolated build environment and fails because there is no 2to3 in that build environment. This is a very old, outdated, unmaintained, and not well-behaved library. If I were you I would not use it at all, if I could.
If you really depend on that library, you could try to tell pip to install it without "build isolation", with
python -m pip install --no-build-isolation --no-deps pyminifier. I am not sure it would help. Maybe it would be better to use an old Python version (not sure which Python version you are using right now). Honestly, I would rather not use this library at all if I were you.
