Reposting Kevin Fries', response with a small clarification as it worked for me.

For those that find this on a google search, install lib yaml with brew, then try your Mise ruby install again.

The command to run is brew install libyaml

This solution worked for me.

MacOS 14.5, MacBook Pro M1.

brew install ruby
brew link --overwrite ruby --force
You will see a terminal warning:

Refusing to link macOS provided/shadowed software: ruby If you need to have ruby first in your PATH, run: echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

For compilers to find ruby you may need to set: export LDFLAGS="-L/usr/local/opt/ruby/lib" export CPPFLAGS="-I/usr/local/opt/ruby/include"

For pkg-config to find ruby you may need to set: export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"

Paste in terminal: echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.zshrc

If you are using zsh, you may need additional steps:

4.1. Configure environment variables for compilers:

echo 'export LDFLAGS="-L/usr/local/opt/ruby/lib"' >> ~/.zshrc

echo 'export CPPFLAGS="-I/usr/local/opt/ruby/include"' >> ~/.zshrc

4.2. Configure the environment variable for pkg-config:

echo 'export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"' >> ~/.zshrc

Reload your terminal.
Check ruby version: ruby -v

I hope you'll see output ruby 3.3.4 or newer.

Hope it helps!

How to specify installation order? · jdx/mise · Discussion #4110

Something similar happens if you try to install Ruby with YJIT support which requires Rust. If you do a blind mise install, mise might install Ruby before Rust so you end up with Ruby without YJIT support thus forcing you to enforce the installation order manually.

January 25, 2025 - You may have wasted hours trying to install ruby with mise but not rails. Mise and rbenv are version managers for ruby and do not manage the installation of rails. More to this point, I have to wonder when you say "when I 'rails -v' i kept saying that it's not installed", I have questions.
