where is ruby 3.0.0 on rbenv

Question

rbenv install --list-all shows me, among many other things of course,

3.0.0-dev
3.0.0-preview1
3.0.0-preview2

But where is 3.0.0 itself, the actual final release? I'd like to try it out. Not all announced features made it into the previews so I need the real thing.

Answer 1

rbenv install passes thru ruby-build. You need to update (brew upgrade if installed via Homebrew) your ruby-build in order to see the latest versions.

Answer 2

On Ubuntu

Short answer:

# You need to update the available versions via ruby-build
~ git -C ~/.rbenv/plugins/ruby-build pull
~ rbenv install 3.0.0
...
Installed ruby-3.0.0 to ~/.rbenv/versions/3.0.0
