For those who any of the above fixes didn't work I installed Python 3.9.1 set it to the global python version (setting it to local version didn't work), and ran bundle again and it installed mini_racer correctly.

What tipped me off was the following message in the console output after it failed:

Python 3.12. Use setuptools or check PEP 632 for potential alternatives
  from distutils.spawn import find_executable
Please use python3.9 or python3.8 or python3.7 or python3.6 or python3.5 or python2.7.
Node.js configure: Found Python 3.10.2...

Here are the commands I ran:

pyenv install 3.9.1
pyenv global 3.9.1
bundle

if someone is using mini_racer 0.3.0 or below, please upgrade to gem 'mini_racer', '0.6.2' and comment out libv8

trust me, it will save you hours of dev config time

Much thanks @gamesover This was the perfect fix for Monterey 12.4 on a M1.

Comment out Following 2 Gems from Gemfile

1: g em 'libv8'
2: gem 'therubyracer'

Add following Gem

gem 'mini_racer'

bundle install

Should work as suggested by @srfinkel
