How to Install JetBrains RubyMine Ruby IDE on Ubuntu

RubyMine is one of the most advanced integrated development environments (IDEs) for the Ruby programming language. Created by JetBrains, RubyMine comes packed with features to help you be more productive in building Ruby and Ruby on Rails applications.

In this comprehensive 2600+ word guide, I will provide expert-level instructions on installing the latest version of RubyMine on Ubuntu 22.04 LTS from start to finish.

Why Choose RubyMine

Before we dive into the installation guide, let me briefly highlight some of the standout features that make RubyMine a top choice among Ruby developers:

Intelligent Code Editor

RubyMine has a smart code editor deeply optimized for Ruby and Rails. It provides:

• Context-aware autocompletion
• On-the-fly code analysis with 300k+ code inspections
• Fast and reliable navigation and search
• Support for Rubocop, Ruby version managers, and more

Combined, these code editing aids help you write better, bug-free Ruby code faster.

Robust Debugging Capabilities

Debugging is invaluable for analyzing the runtime behavior of Ruby apps. RubyMine makes debugging easy with:

• Line breakpoints
• Smart step filtering of framework code
• Frames view displaying call stacks
• Handy debugger console
• Live evaluation of variables and expressions
• Plus visual debugging tools for client-side Ruby code

You can seamlessly go from editing to debugging Ruby apps using RubyMine‘s polished user interfaces.

Built-in DevOps Tools

In addition to coding features, RubyMine provides out-of-the-box integration with various developer tools:

• Version control systems like Git, SVN, Mercurial
• REST client for sending HTTP requests
• Database tools supporting MySQL, Postgres, and more
• Remote interpreters letting you run apps on dev servers
• Terminal for running shell commands within the IDE

These DevOps capabilities streamline your end-to-end workflow.

Cross-technology Support

RubyMine understands that Ruby developers often use many technologies like JavaScript, SQL, Docker etc. So it includes competent editors and assistants for these additional languages too.

You get coding productivity across multiple connected technologies – all accessible from RubyMine‘s unified GUI.

There are plenty of other small and big conveniences packed into this feature-rich IDE. It brings immense value no matter if you are just starting in Ruby or are a seasoned expert developer.

Now let‘s get RubyMine installed on Ubuntu!

Step 1 – Install Ruby (If Needed)

Since RubyMine is a Ruby IDE, you need to have Ruby available on your system.

Here are quick instructions to install or upgrade Ruby on Ubuntu 22.04 LTS:

Installing Ruby

Run the following apt commands in a terminal to install Ruby:

sudo apt update
sudo apt install ruby-full

Select Y when prompted to continue with the installation.

Upgrading Ruby

If Ruby is already present, update it to the latest stable version:

sudo apt install ruby-full --only-upgrade

Verify you have a supported Ruby version (>= 2.3) with:

ruby -v

And that‘s it! The Ruby requirement for RubyMine is now fulfilled.

Step 2 – Download the RubyMine Linux Installer

Navigate to RubyMine‘s Download Page in your browser.

Under the Linux section, click on the Debian/Ubuntu package link matching your Ubuntu architecture.

For most users, the 64-bit .tar.gz file is recommended. But select 32-bit if you have a legacy 32-bit system.

The download should begin instantly. Save the .tar.gz bundle to your home or downloads directory.

Step 3 – Extract the RubyMine Bundle

Go to your terminal and use cd to enter the location where RubyMine-<version>.tar.gz is downloaded.

Extract this bundle using the tar command:

tar xfz RubyMine-<version>.tar.gz

This will unpack the installer contents into a folder like RubyMine-2022.3.1.

Enter this newly created directory:

cd RubyMine-2022.3.1/bin

And confirm there is a rubymine.sh startup script present.

Step 4 – Install RubyMine‘s System Requirements

Before launching the IDE, you need to set up RubyMine‘s required runtime dependencies manually.

Run the following commands to install them:

sudo apt install libgtk2.0-0 libpcsclite1 libxtst6 libnss3 libnspr4 libxss1 libasound2

Additionally, a suitable Java runtime >= 8 is required. You can install OpenJDK 11 by using:

sudo apt install openjdk-11-jre

That completes the system requirements. RubyMine is now prepared to launch on your Ubuntu desktop!

Step 5 – Launch RubyMine

It‘s time to open RubyMine for the very first time!

Switch to RubyMine‘s bin path and execute its start script:

./rubymine.sh

This will initialize RubyMine and take you through the first-time setup wizard.

First, select to not import any settings and proceed:

Next, accept JetBrains‘ EULA license agreement:

Then pick an UI theme of your choice and continue:

After that, decide which bundled tools and plugins to install or skip.

Finally, you have to activate RubyMine with either a:

• Paid license if you have purchased it
• 30-day free evaluation license

Complete the activation process by signing in with your JetBrains account:

The RubyMine IDE will then fully load for usage!

Step 6 – Create Your First Ruby Project

Let‘s create your first Ruby project inside the configured RubyMine IDE.

From the startup wizard, click on Create New Project:

On the next screen, set Project name as hello_world_app and choose project type as Plain.

Specify the local path where your project files will be stored. Also check if the correct Ruby SDK is picked:

Hit Create and a skeleton hello_world_app directory with empty README file is made!

Step 7 – Write Your First Ruby Program

Expand the project tree on the left pane to see its contents.

Let‘s make a super simple Ruby script that prints "Hello World!".

Right click on the project folder and select New > Ruby File. Name it hello.rb.

In the empty .rb file, add the code:

puts "Hello World!"

This uses the Kernel#puts method to display output.

Save changes and run the script by clicking the green play toolbar button. Or navigate to Run > Run File in Context Menu.

The "Hello World!" message should display in the output console at the bottom!

Hooray! You have successfully written and executed your first Ruby program within JetBrains RubyMine in Ubuntu.
