The problem with rvm was always that it tried to do too much.  With a tool like that, as long as it&#x27;s working, you won&#x27;t see the downside.  When it breaks, it breaks in complicated, hard-to-debug ways.  If you&#x27;re saying it&#x27;s reliable for you, that&#x27;s great.  That wasn&#x27;t my experience.
