How to setup ruby development for mac

To set up Ruby development on a Mac, there are several steps that need to be followed.
However, if you only want to experiment with Ruby language and don’t require multiple versions of Ruby,
you can use Homebrew to install Ruby and explore Ruby’s magic.
Simply use Homebrew to install Ruby and get started!

use homebrew to install ruby

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
brew install ruby

And if require to use multiple versions of ruby then a version manager like rbenv or RVM will help
you. you can follow the below steps:

Install Xcode Command Line Tools

xcode-select --install

use ruby package manager

I am using rvm package manager

\curl -sSL https://get.rvm.io | bash

source ${HOME}/.rvm/scripts/rvm

rvm -v # should return the rvm version details

setup rvm

First install GPG keys

# more detials about rvm here https://rvm.io/rvm/install
# install rvm
\curl -sSL https://get.rvm.io | bash

# load rvm in current open terminal window
source ${HOME}/.rvm/scripts/rvm

# check rvm vesion
rvm -v

Install ruby

we will be using the latest ruby available for the development
and old version might not work based on your mac os version :(

rvm list known will return all available ruby versions for your system

# list all available ruby versions for the current system

rvm list known

rvm install ruby-3.0.2

install Bundler

Bundler is a dependency manager for Ruby projects.

gem install bundler

Now you have Ruby installed on your Mac, and you can start developing Ruby applications
