Just installed Ruby 2.1.3 on my iMac (10.10.2) with ruby-install through Homebrew. I've already been using ruby 2.0.0p481, but just installed Rails too and wanted to update Ruby. As I said, ruby-install did install Ruby 2.1.3, but when I use 'ruby-v' I still get ruby 2.0.0p481. I want to use 2.1.3 though and can't see why it's not being used after being installed.

Thanks.

Try brew link Ruby, which should link your Ruby from home brew with the Ruby you use on the command line.

    Thought this would work, but I get an "Error: No such keg: /usr/local/Cellar/ruby" – Tom McCarthy Jul 24 '15 at 10:39
  • Did you first install just Ruby through Homebrew? 'brew install ruby' – nonamorando Jul 24 '15 at 11:06
  • I've tried that and then 'brew link ruby,' but it didn't work. I then tried 'brew unlink ruby && brew link ruby' as advised by Homebrew on the Terminal, but ruby -v still returned 'ruby 2.0.0 ...' – Tom McCarthy Jul 26 '15 at 18:22
