Introduction

Ruby is a dynamic, open source programming language with a focus on simplicity and productivity. To install Ruby we are going to use RVM (ruby Version Manager). This installation differs from other as you don't run it with user privilegs, that means no more sudoing for this guide.

Requirements

• Ubuntu server

Installation

First install RVM with the latest stable release version of Ruby by fetching the RVM install script with curl.

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

After the installation add you current user to the rvm group.

sudo adduser [username] rmv

For the same user add the rvm startup script to the bash profile.

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

Now log out from the cli and log in to load RVM properly.

Check the installed RVM version.

rvm -v

As RubyGems comes as built-in extension to RVM we don't need to install it.

If everything's ok clone RubyGems from GitHub.
