How to update Ruby with Homebrew?

Question

I want to know how to update to the latest stable version of Ruby with Homebrew. I am not interested in using RVM. Thanks.

Answer 1

I would use ruby-build with rbenv. The following lines install Ruby 2.7.2 and set it as your default Ruby version:

$ brew update
$ brew install ruby-build
$ brew install rbenv

$ rbenv install 2.7.2
$ rbenv global 2.7.2

Answer 2

open terminal

\curl -sSL https://get.rvm.io | bash -s stable

restart terminal then

rvm install ruby-2.4.2

check ruby version it should be 2.4.2

Answer 3

brew upgrade ruby

Should pull latest version of the package and install it.

brew update updates brew itself, not packages (formulas they call it)

Answer 4

Adding to the selected answer (as I haven't enough rep to add comment), one way to see the list of available versions (from ref) try:

$ rbenv install -l

Answer 5

To upgrade Ruby with rbenv: Per the rbenv README

• Update first: brew upgrade rbenv ruby-build
• See list of Ruby versions: versions available: rbenv install -l
• Install: rbenv install <selected version>
