Installing Ruby on Ubuntu

As seen on RVM

Go to the terminal in Ubuntu.

Add the public key from RVM

$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

$ \curl -sSL https://get.rvm.io | bash -s stable

On the Terminal go to the Menu/Edit/Profile Preferences/Title and Command.

Check “Run command as a login shell”.

Close the Terminal and start a new one.

$ type rvm | head -n 1

This should now say rvm is a function

Install Ruby. As of 10/20/16 the stable version was 2.3.1

$ rvm install 2.3.1

$ rvm use 2.3.1 --default

Use Gemsets

To work on different projects create a Gemset as seen here.

$ rvm use 2.3.1@name-of-project --create

List gemsets with:

$ rvm gemset list

Switch gemsets with:

$ rvm gemset use name-of-gemset
