Updating Ruby

Hi, I am new to Digital Ocean. I am try to set up an application using ruby-2.1.1. I have created a droplet with ruby on rails

Running ruby -v display ruby-2.0.0-p353

to update ruby to 2.1.1 i have ran the following commands

rvm install 2.1.1 rvm use ruby-2.1.1 --default gem install rails -v 4.0.3 rvm gemset create Rails4.0.3 rvm use ruby-2.1.1@Rails4.0.3

I then created a new app call myapp

I have updated the app paths in /etc/default/unicorn and /etc/default/unicorn to point to the myapp directory

I then set the etc/default/unicorn path to

PATH=/usr/local/rvm/rubies/ruby-2.1.1/bin:/usr/local/rvm/gems/ruby-2.1.1/bin:/home/unicorn/.rvm/bin:/usr/local/sbin:/usr/bin:/bin:/sbin:$

When i restart unicorn i get lots of ruby-2.0.0-p353 errors. What am i missing?
