I'm new to Ruby, and had the 2.0.0 version of Ruby on my mac by default. I was trying to get the latest version, and followed this question: How to update Ruby to 1.9.x on Mac?, but even then, the latest version remains 2.0.0. I copied some of the terminal commands I used:

Manish-MBP:~ manishgiri$ brew update
Error: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. Some versions of the
"InstantOn" component of Airfoil are known to do this.
You should probably change the ownership and permissions of /usr/local
back to your user account.

It looked like there was an issue with homebrew, so I decided to update it. I did the change ownership and permissions part, and followed the instructions on this question - How do I update Homebrew? and executed brew update. I got an Already upto date response.
Next, I tried rvm list known from the first answer, just to verify the latest version, and following that I executed rvm install current && rvm use current. I got this response:

Now using system ruby.
After all of that, I thought it would have upgraded to 2.2.3 but when I ran ruby -v, I still got: ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15].
Why did the update fail? I have installed RubyInstaller on my windows PC and that uses 2.2.3.
