I am reading the book Programming Ruby and am looking to upgrade the version of Ruby on my computer. I run Mac OS X Snow Leopard and doing ruby -v in the command line shows I am running Ruby. We will be setting up a Ruby on Rails development environment on macOS 10.15 Catalina. Older versions of OS are mostly compatible so follow along as far as you can and then Google search for any problems you run into. There are plenty of people who have documented. Upgrade Your System to OS X Mavericks. Installing Ruby on Rails is simple, but unless you have an. Set up a Mac for Ruby Dev. The SSD on my Air died this weekend, no backup. This time when setting a new system up I took note of all the steps. All the steps were tested on the latest Mac OS X 10.8.3 (latest). Apple compiler toolchain Install XCode from App Store (1.9 GB).

This article explains why you should avoid using the version of Ruby bundled with Mac OS X and should instead install your own version of Ruby with RVM, the Ruby Version Manager.

Hands Off the System Ruby

Apple bundles the Ruby programming language with OS X. However, the main caveat for using the bundled version, called the system Ruby, is that Apple bundles Ruby for it’s own use. Therefore, it’s best not to make changes to the system Ruby.

You’ll know when you’re about to change the system Ruby when you need to prefix a gem installation with sudo, for example:

Mac upgrade ruby

Another reason for not using the system Ruby is that it’s often several versions behind the latest stable version.

The Ruby Version Manager

A better alternative to using the system Ruby is to install Ruby with RVM, the Ruby Version Manager. RVM is a tool for installing different versions of Ruby itself. RVM has the following advantages:

  1. RVM enables you to install multiple versions of Ruby and allows you to change which version you want to use.
  2. RVM installs each version of Ruby in a hidden folder in your home folder so each version of Ruby you install doesn’t affect the system Ruby.
  3. Gems installed by RVM-managed versions of Ruby are installed within the hidden folder in your home folder containing that version of Ruby.
  4. You won’t need use sudo to install gems.

To check that you’re currently using the system Ruby, open Terminal and type the following:

If you’re using the system Ruby, OS X will respond with:

You can check which version of Ruby OS X is using with:

Installing RVM and Ruby

The RVM install page has comprehensive instructions for installing RVM that work on Mac OS X. I’ll provide the steps I used here.

The first step is to install the mpapis public key. However, as the install page notes, you might need gpg. Mac OS X doesn’t ship with gpg so before installing the public key, you’ll need to install gpg. I installed gpg with Homebrew:

After you’ve installed gpg, you can install the mpapis public key:

I've listed the mapis public key install command here for illustration. You should use the version on the RVM install page.

I chose to install RVM with the latest stable version of Ruby, which at the time was 2.2.0:

After the installation completes, close the Terminal window and open a new one to make sure that Terminal picks up any environment changes.

The rvm use command selects a version of Ruby:

Ruby Mac Os Update

You can check that you’re using an RVM-managed version of Ruby with:

OS X now responds with:

Ruby For Mac Os

which tells us we’re using version 2.2.0 and that version 2.2.0 has been installed in my home folder away from the system Ruby. You can confirm this by asking Ruby itself with:

The RVM-managed version of Ruby responds with:

As I mentioned earlier, gems installed with RVM-managed versions of Ruby are located with the Ruby. You can check where gems will be installed with:

The following lines of output shows that gems will be installed in the folder XXX.

Ruby Programming Language

To find out where a particular gem is installed, use the gem which command. For example, gem which jekyll locates the Jekyll gem:
