RVM - Do I need Ruby 1.8.7 to install Ruby 1.9?

I just need to clarify the line that I read after running rvm requirements . It says:

 To install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head), then you must install and use rvm 1.8.7 first.

Does this mean RVM version 1.8.7 or Ruby version 1.8.7? I am currently running RVM version 1.10.2 without installing gems, but I want to install only 1.9.3. Thanks!

Just by looking at the latest version of this part of RVM , it looks like you get this message automatically. It targets users * nix, so I can not check it at the moment, but all such users should receive this message from rvm requirements . He has been there since September last year, and this is not a warning that you did not meet the addiction. (Note that he also says that bash, curl, git, and patch are required, and you probably have those.)

In any case, this refers to the RVM version, which for you is the two minor versions. This is a clear confusing message, since 1.8.7 is also a fairly common version of Ruby.

This means RVM version 1.8.7, not Ruby 1.8.7.
