Subject: install ruby 1.9.3 on Mac

I would like to upgrade my actual ruby version 1.8.7 installed on my Mac
to 1.9.3 or 1.9.2
I read lots of things searching on google I found information at
https://rvm.io/rvm/install

Then I tried the upgrade as follow:

source ~/.rvm/scripts/rvm

rvm list known

rvm install 1.9.3

which ruby

ruby -v

I even add the command rvm use 1.9.3 --default

That sound work untill I close the terminal and reopen it again. When I
reopened the terminal, the ruby version 1.9.3 was no longer available,
only the old version. Worse of all, even the RVM command is not
recognized.
I am a Biologist that has fun to code in Ruby. Could you guys help me to
fix it in a very straight forward way?
Thanks in advance
