Why would `rvm install ruby-2.1.0` install preview1?

Question

I just tried to install Ruby 2.1, and instead got 2.1 Preview 1. This seems crazy to me. 2.1 is out. Why would RVM assume that when I say rvm install ruby-2.1.0 that I really mean rvm install ruby-2.1.0-preview1? Why would it not match the exact version I specified, instead of one which begins with that substring?

Answer 1

Silly clarification question (and I would post it as a comment if I had enough reputation), but have you updated RVM lately?

rvm get stable (or if you want to live on the edge, rvm get head) would, I expect, update the internal list of released ruby versions.

Answer 2

Make sure you are running the latest version. RVM 1.25.8 (or greater) is working as expected.

$ rvm get latest
Downloading https://github.com/wayneeseguin/rvm/archive/1.25.8.tar.gz

and

$ rvm install 2.1
Searching for binary rubies, this might take some time.
...
ruby-2.1.0 - #downloading ruby-2.1.0, this may take a while depending on your connection...

and

$ rvm use 2.1
Using /Users/weppos/.rvm/gems/ruby-2.1.0
$ ruby --version
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin13.0]
