Ruby Bundle Install Not Working. Can't Install Racc - ruby-on-rails

Question

Using my macOS Monterey v12.6, I'm trying to run Bundle Install in my Ruby on Rails projects and it stops working.
This is the message I get when I get after it stops.

An error occurred while installing racc (1.6.0), and Bundler cannot continue.
Make sure that `gem install racc -v '1.6.0' --source 'https://rubygems.org/'` succeeds before bundling.

I tried running rails -v and this is the response to that:

Anyways, Rails in Gemfile:
gem 'rails', '~> 6.1.4', '>= 6.0.4.6'
I already tried solving the issue by doing the solution from this post and it didn't solve it.
Does anyone know what's happening and how shall I solve it?

Answer 1

After installing XCode dev tools via the terminal running command xcode-select --install, I went to System Preferences -> Software Update and updated ran the updates to the OS shown after installing XCode.
It is important to make sure Developer Tools have the authorization to use Terminal.
After updating macOS, run xcodebuild -runFirstLaunch and you'll finally be able to successfully run Bundle Install and Bundle Update in your Ruby projects.
