So previously when we were setting up Rails we installed Ruby, so in this post we are going to go over how you would update your Ruby version.
As you may remember we are using rbenv to manage our Ruby versions. And this was installed on top of Homebrew.
The following lines are used to install Ruby 2.7.2 (check ruby-lang.org for the latest version) and set it as your default Ruby version:
brew update
brew upgrade ruby-build
rbenv install 2.7.2
rbenv global 2.7.2
# version should be >= Ruby 2.7.2
ruby -v
An that’s it, you’ve updated Ruby to the latest version.
