From what I recall, pik is also an option if you want to manage multiple
Ruby versions on Windows. Similar to rvm. I personally avoid windows
when developing with Ruby or Rails, but clients still require it in some
cases.
RubyInstaller if you are just starting out. Then I’d use pik as more
releases come out or you have an older Rails app you are working on or
you want experiment with more than MRI version like Jruby, rubinis, etc.
