MRI – Matz’s Ruby Interpreter
1. We need curl on a fresh install if it so happens that it is not present:
sudo apt-get update
sudo apt-get install curl
2. Download and run the RVM installation script
2.1 Installing the stable release version:
user$: curl -sSL https://get.rvm.io | bash -s stable
2.2 To get the latest development state:
user$: curl -sSL https://get.rvm.io | bash
3. Reopen terminal and run:
rvm install ruby-2.1.0
or paste this in the current terminal and then install ruby: source ~/.rvm/scripts/rvm
4. If you’re getting the “RVM is not a function” message you need to enable login shell (optional):
With the the terminal window open go to:
Terminal > Edit > Profile Preferences > Title and Command > Run command as a login shell (make sure this check-box is enabled)
