ruby-on-rails - rvm command not found

Question

I installed rvm with rails, from the official website of RVM, I specified the command suggested by the tutorial. When the installation my system has rails 4.0.0, rvm 01/23/12, ruby 2.0.0, bundler gem 1.3.5 and 2.0.3 But I need to install ruby 1.9 to practice with a course that I am currently doing. "Rails for Zombies 2" I try to execute the instruction rvm install 1.9.3 and the console returns this message: rvm: command not found

Your problem is that RVM is not loaded when you open a new terminal.

To solve this, run this command line: (if using login-shell)

echo "source $HOME/.rvm/scripts/rvm" >> ~/.bash_profile

Or this (if using non-login shell):

echo "source $HOME/.rvm/scripts/rvm" >> ~/.bashrc

Or if you are using zsh (and/or oh-my-zsh):

echo "source $HOME/.rvm/scripts/rvm" >> ~/.zshrc

This will add the path to RVM to load at each Terminal instantiation. You must either close and reopen your terminals or simply call source ~/.bashrc (or ~/.bash_profile or ~/.zshrc).

I had this problem after installing zsh. I'm a domain user so my $PATH and $HOME are not as straight-forward. What worked for me was

echo "source /usr/share/rvm/scripts/rvm" >> ~/.zshrc
