As someone who clearly doesn&#x27;t use Ruby often enough to &quot;get it&quot;, I don&#x27;t understand this problem: I have multiple major versions of Ruby installed on my server from Ubuntu via APT, and I don&#x27;t need to &quot;switch&quot; between them... they are just versions in their install names like all the other versioned interpreters I install. If I want some kind of &quot;default&quot; build of Ruby, that seems like it would be solved with nothing more than a three line shell script to build either aliases or symlinks (and I think Ubuntu already has a way to do this using diversions).
