Ruby brain

Don’t install ruby directly like this

brew install ruby

then install bundle with

sudo gem install bundler

Instead, you should install using RBenv with brew install rbenv-bundler then go to the root dir of your ruby codebase and do

rbenv init
rbenv install 3.1.2 #install version 3.1.2 of Ruby
rbenv local 3.1.2 # set local to use this versoin

Then we can install gems like bundle

gem install bundle
