Step 1: Install required tools

(First step of Tutorial: Ruby in AWS Cloud9)

In this step, you install Ruby, which is required to run this tutorial.

1. In a terminal session in the AWS Cloud9 IDE, confirm whether Ruby is already installed by running the ruby --version command. (To start a new terminal session, on the menu bar, choose Window, New Terminal.) If successful, the output contains the Ruby version number. If Ruby is installed, skip ahead to Step 2: Add code.

2. Run the yum update for (Amazon Linux) or apt update for (Ubuntu Server) command to help ensure the latest security updates and bug fixes are installed.

   For Amazon Linux:

   sudo yum -y update

   For Ubuntu Server:

   sudo apt update

3. Install Ruby by running the install command.

   For Amazon Linux:

   sudo yum -y install ruby

   For Ubuntu Server:

   sudo apt install -y ruby
