如何使用rbenv安装Ruby 2.5.1

Question

I am trying to install Ruby and rbenv but I keep running into errors. I tried researching solutions here and attempted several but did not have success.

Whenever I attempt to download I get:

Downloading ruby-2.5.1.tar.bz2...

-> https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.1.tar.bz2

you should be installing latest stable ruby version 2.7 in your machine instead of old versions.
