I would use ruby-build with rbenv. The following lines install Ruby 3.1.3 and set it as your default Ruby version:

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


$ rbenv install 3.1.3
$ rbenv global 3.1.3

最佳答案

brew upgrade ruby

Should pull latest version of the package and install it.

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

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

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>
