How to install ruby on Ubuntu 22.04 VM (VirtualBox)

Today, let’s explore how to install ruby on your Ubuntu 22.04 Box, and run a test script to print Hello World!

Step #1 Prepare your Ubuntu for Ruby installation

As always, it is recommended to start with updating your Ubuntu package index.

sudo apt update

Step #2 Run the package installation step

Run the ruby installation command using apt

sudo apt install ruby-full -y

With this, you have your latest ruby development environment ready. Next, go on and test it.

Step #3 Check the installation version & test run the ruby hello world

Although you could see which version is being installed when you run the apt command, later to get the installation version any time, you can check using the ruby -v command

dev@codetryout:~$ ruby -v
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [x86_64-linux-gnu]

Let’s create our first ruby script.

echo 'puts "Hello CodeTryout" ' > myscript.rb

Testing the hello-world program.

ruby myscript.rb

This will run and output like:

dev@codetryout:~$ ruby myscript.rb
Hello CodeTryout
ruby on Ubuntu, hello world!

Try ruby without installing it

I found this resource very helpful to try ruby in your browser without installing it.

Try Ruby online

I have tried and tested these ruby installation steps on Ubuntu Virtualbox, Ubuntu version 20.04, and the exact steps will work on Ubuntu 22.04 as well.

Good luck with your ruby programming!
