Updating Ruby on Yosemite

Mac OS X Yosemite came with Ruby 2.0 out of the box, so I thought that I would like to update it to one of the latest stable builds: 2.2. I came across posts talking about Ruby Version Manager (rvm) and decided to install Ruby 2.2 using it. The rvm site has a good installation guide but I filtered out what I actually needed.

Firstly, I opened up Terminal.app to check on my Ruby version with
ruby -v

Then I ran the following line to install rvm
\curl -L https://get.rvm.io | bash -s stable –ruby

Post installation, I restarted Terminal and ran the following to display a list of all known rubies
rvm list known

To install a version of Ruby, I went with
rvm install 2.2

Once the installation has been completed, I checked my Ruby version again

Mac:~ user$ ruby -v  
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-darwin14]  

Great! Now I am updated to Ruby 2.2.
