Restart the Terminal, or write: 1 source ~/.bash_profile Next, we are ready to install rbenv: 1 brew install rbenv 2 rbenv init 3 echo 'if which rbenv > /dev/null then eval "$(rbenv init -)" fi' > ~/.bash_profile In order to install rbenv we need to install Homebrew first: 1 /usr/bin/ruby -e "$(curl -fsSL )" The idea is to keep the system Ruby untouched and have a more modern version available. Easiest way to have an up-to-date Ruby installed on macOS is to install rbenv which will let you chose between Ruby installations. However, latest stable version of Ruby, 2.5.1, is faster and more up-to-date. Once the Command Line Tools are installed you will have a relatively new version of Ruby installed on your machine, 2.3 at the time of this writing.
Open a Terminal and write: 1 xcode-select -install
Please note, that you will need the Command Line Tools even if you’ve already installed Xcode. Start by installing the Command Line Tools for macOS. In this article I will show you how to install the latest stable version of Ruby, which is 2.5.1 at the time of this writing, on macOS, Windows 10 and Ubuntu 18.04.
