Open your terminal and run
curl -sSL https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer | bash -s stable

Now, run rvm list known
This shows the list of versions of the ruby.
Now, run rvm install ruby@latest

.
If it still shows you ruby 2.0.
, run rvm use ruby-X.X.X --default
.
