Fixing Gem Install Errors on M3 Mac with Ruby 2.7 · Daniela Baron

Starting a new role always comes with exciting challenges, and one of my first tasks in a recent new role was setting up a 10-year-old legacy Rails project on an M3 MacBook. The project was running Rails 6.1 and Ruby 2.7.8, with several older versions of gems that errored on bundle install. In this post I'll share what caused the errors, and the steps to resolve them, so you can save time and headaches when faced with similar issues.
