Ruby Rails Install Guide for MacOS Ventura

Step 1: Install Homebrew

Run this command inside your terminal to install Homebrew:

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

Step 2: Install Ruby

MacOS comes with Ruby pre-installed but we're going to use Homebrew to get the latest version.

To install Ruby with Homebrew, run:

brew install ruby

Step 3: Add Ruby to Path:

Now we need to add this installation to our path so that its used instead of the default MacOS one.

1. Get the location of your Homebrew installed Ruby:

brew info ruby

2. Get the location of your gems:

gem environment gemdir

3. Use those to run the following command to prepend those locations to your path:

echo 'export PATH="{your-ruby-location}:{your-gem-location}:$PATH"' >> ~/.zshrc

Note Depending on your shell, you might need to replace ~/.zshrc with ~/.bashrc or ~/.bash_profile, etc.

Mine looked like this:

echo 'export PATH="/opt/homebrew/opt/ruby/bin:/opt/homebrew/lib/ruby/gems/3.2.0/bin:$PATH"' >> ~/.zshrc

Restart your terminal and run:

which ruby

to verify that it points to the Homebrew installed Ruby.

Step 4: Install Ruby on Rails

Run the following to install Ruby on Rails:

gem install rails

Restart your terminal and you should be good to go!
