The reason why some version managers can't install certain versions of Ruby is because they all compile Ruby from scratch, and whether or not the installation succeeds depends on five main factors: The problem is that these version managers (when used out of the box with their default settings) fail to install Ruby 2.6.x on any Mac running on macOS Ventura (13.x), and in some cases on the latest version of Monterey (12.6.x) that has version 14 or higher of Apple's command line tools (CLT).Īssuming you have Homebrew installed, you can check which version of the CLT you have by running `brew config`, and then look towards the bottom for the lines that start with "CLT:" and/or "Xcode:" The most popular ones are asdf, chruby/ruby-install, frum, rbenv/ruby-build, and rvm. These tools, known as version managers, can install multiple versions of Ruby at the same time, and let you easily switch between them. Instead, you'll want to use a special tool that can install a separate version of Ruby that doesn't interfere with the one that Apple installed. Read my article that goes over 5 reasons why you shouldn't use the system Ruby on macOS. However, this version of Ruby preinstalled by Apple is not meant to be used for development. That proves that it is possible to install it on Ventura on both Intel and Apple Silicon Macs. Yet, Ventura comes preinstalled with Ruby 2.6.10 on all Macs. Some people will tell you that Ruby 2.6 is not compatible with Apple Silicon Macs. This is super important to understand, so please read my guide that explains how and why to upgrade the Ruby version in your project. Note that you can also go straight from 2.6.x to 2.7.7. And then the next thing you want to prioritize is updating it to 2.7.7 because Ruby 2.6 reached end of life in March 2022, which means it has known bugs and security issues that will never be fixed. Instead, it's recommended to update the project to at least the latest patch version (the third digit).įor example, if your project is currently using Ruby 2.6.6, or any version of 2.6 lower than 2.6.10, the first thing I recommend you do is update it to 2.6.10. They get stuck because they think they have to use the version of Ruby that's specified in the project's `.ruby-version` and/or `Gemfile`. This is another common source of confusion because people don't understand how Ruby versioning works. Wait, do your solutions only work with 2.6.10? I need an older version! Downgrade to version 13.4 of the command line tools (only possible on Monterey or older).Install Ruby 2.6.10 with Ruby on Mac Ultimate.In this article, I'll show you 3 different ways to install Ruby 2.6 on an Apple Silicon Mac: Understandably, they conclude that it's impossible, but that's because most people are not experts in Ruby installation. People try all kinds of things but no one seems to be able to succeed. I get asked this question a lot, and I see it often in the various online Ruby hangouts. "How can I install Ruby 2.6.x on an Apple Silicon Mac (M1/M2)?"
