title: What are the alternatives to Ruby Version Manager (rvm)?
body: <p>rvm had a substantial impact on ruby programming and for a long time brought lasting benefits to us, but honestly I need to stay agile and informed about other possibilities at this point. Lately I only get one version of Ruby to manage so I'm not sure if the benefit is outweighing the cost of configuration. </p>
  
  <p>One alternative, <a href="https://github.com/sstephenson/rbenv" rel="noreferrer">rbenv</a>, has worked well for me. rbenv is an alternative because it let's us set the global ruby version on a per-user basis, and like rvm offers support for per-project Ruby versions. Also you can override the Ruby version with an environment variable. I do not know what it's like yet to use <a href="https://github.com/jayferd/ry" rel="noreferrer">ry</a>. If anyone has used ry or the other alternatives, please share any knowledge or experience on this question I feel is important. I am always interested in things I have not heard of and knowing more about some of these alternatives to Ruby Version Manager (rvm). Also I feel grateful for Stackoverflow.com and this area of the internet's wealth of knowledge. Thank you.</p>
