@eveevans so you could not get this to work in standard homebrew?

@chrishough yes indeed, I'm using ASDF for Ruby (and Node)

@eveevans from your command list I originally read that using arch linux, but I am new to asdf

@chrishough you will need brew, but the thing about it, is that there are two versions of homebrew for Silicon macs, the one for ARM (by default), and the one for Intel (which needs to be run under Rosetta)

In the time I installed Ruby there were a lot of Brew package unavailable for ARM. So I used the Intel version (X86) in order to install the X86 version of ASDF, using X86 dependencies

(In my case, I was using and old Ruby that needed old dependencies)

@eveevans I am having this issue on both an M1 and non-m1 machine, trying to fix the non-m1 first

I worked on this work around. It worked for me and I've never had any issues.
It's kinda long but a Turing instructor and I worked on this.
One of the answers in the answers also might work too

On my Apple M1 with MySQL 5.7 and OpenSSL@1.1 with Ruby 2.6.5.x

   
    bundle config build.mysql2
      --with-mysql-config=/opt/homebrew/Cellar/mysql@5.7/5.7.36/bin/mysql_config
      --with-ldflags=-L/opt/homebrew/opt/openssl@1.1/lib 
      --with-cppflags=-I/opt/homebrew/opt/openssl@1.1/include

   bundle install  # installed mysql2 with native gems just fine

After hours of dealing with this, I finally found a solution that worked for me. Big Sur 11.6 - Intel

env \ CXX=clang++ \ GYPFLAGS=-Dmac_deployment_target=10.9 \ gem install libv8 --version 3.16.14.19

then run bundle install

Hope this helps!

This one worked for me as well! Thank you very much

macOS Monterey doesn't include Python 2 anymore. Python 2 is required by libv8. To install it (from https://www.alfredapp.com/help/kb/python-2-monterey/), execute the following (preferably in a new shell because it changes $PATH):

export PATH="/opt/homebrew/bin:/usr/local/bin:${PATH}"
eval "$(brew shellenv)"
brew install pyenv
pyenv install 2.7.18
ln -s "${HOME}/.pyenv/versions/2.7.18/bin/python2.7" "${HOMEBREW_PREFIX}/bin/python"

For Ruby 3.0.4 in Monterey (macOS 12.3.1), this worked for me:

brew install v8@3.15
bundle config build.libv8 --with-system-v8
bundle config build.therubyracer --with-v8-dir=$(brew --prefix v8@3.15)
bundle install

Unfortunately, it's not so easy in Ruby. 3.1. That includes psych-4 as a "default" (hard-coded in) gem which can't be removed, and psych-4 is incompatible with libv8 (for now at least). I have not found a solution to this, aside from reverting to ruby 3.0.4.

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
