11,940 PointsUpdated to the newest version of Ruby, but typing ruby -v returns the old version. Do I actually have the new version?
The installation of Ruby 2.1.2 went fine, no errors. But as the title says, when checking to see if Ruby 2.1.2 is actually installed, ruby -v returns 2.0.0p451.
So I assume something went wrong, but what exactly is it, and how do I fix it?
Thanks

rvm --default use 2.1.2
You can have multiple versions of ruby installed at the same time. Now it uses default version 2.0.0. You can read this blog post for more information: http://rvm.io/rubies/default
