Ruby on Rails is a web development framework written in Ruby that helps developers build websites and applications quickly. It uses an MVC (Model-View-Controller) structure to organize code and make everyday tasks easier by following simple patterns instead of complex configurations. Rails also helps with database management and includes security features to protect against common threats. It's famous for building websites and apps, especially for startups, and powers well-known platforms like GitHub and Shopify.
This blog post will walk you through 10 simple steps to get your Ruby on Rails development environment up and running while providing additional resources to help you with your Ruby on Rails journey.
Setting up your Ruby on Rails development environment will take roughly 30 minutes from start to finish.
Enabling WSL will allow us to install and run Ubuntu. Ubuntu is a Linux distribution that is considered one of the easiest to use and has a lot of documentation, making it a good choice for setting up a Ruby on Rails development environment. Most of the code written with Ruby on Rails will run on a Linux server, so using Ubuntu can help ensure the development environment matches the production server.
1.1 To enable WSL within our Windows system, we will navigate to the Windows search console and type “Turn Windows features on or off.” Select the Turn Windows features on or off option.
1.2 Within this window, you will scroll down until you find “Windows Subsystem for Linux.” Check the box on the left side to ensure this feature is enabled.
1.3 Once you have enabled WSL, Windows will download the required dependencies. Upon completion, you will be prompted to restart your computer. Restart your computer at this time.
Downloading Ubuntu from the Microsoft Store is a convenient way to run Ubuntu on your Windows machine without the need for dual-booting or using virtual machines. It runs through the Windows Subsystem for Linux (WSL), which allows you to use a complete Ubuntu terminal environment inside Windows.
DO NOT install the generic "Ubuntu" app. Please install an LTS version. The generic version runs as root. We need an LTS version with the proper user, role, and permissions.
2.2 Download the latest version of Ubuntu LTS. Once downloaded, open your Ubuntu terminal and allow Ubuntu to complete the installation. This may take a few minutes to complete.
2.3 Enter a username and password for your Ubuntu installation.
To get started with your Ruby install, we will install all the required dependencies for compiling Ruby within a Linux system. We will update the software packages using the Advanced Packaging Tool (APT) that are already in our terminal.
3.1 Open your Ubuntu terminal and run the following command to update your package list:
3.2 Now run the following command to download all the required Ruby dependencies.
4.1 Install the asdf version manager by running the following commands in your Ubuntu terminal. Run each command separately.
4.2 Add the Ruby and Node.js plugins by running the following commands in your Ubuntu Terminal. Run each command separately.
5.1 To install Ruby, we will first check for the most recent version by running the following command:
This will list the latest stable version of Ruby. We recommended the most recent version. 5.2 Install your chosen version of Ruby with the following command:
5.3 Set your selected version as your default.
5.4 Confirm your Ruby version
6.1 To install Node.js, we will first check for the most recent version by running the following command:
This will list the latest stable version of Node.js.
6.2 Install your selected version of Node.js with the following command:
6.3 Set your selected version as your default.
6.4 Confirm your Node.js version
Git is a standard tool in the software development industry for version control. We will set up our Ruby on Rails development environment to utilize Git as our version control.
7.2 Configure your Git by running the following commands in your Ubuntu terminal:
Run each command individually, replacing placeholders with your actual information. 7.3 Generate an SSH key with the following command:
Click New SSH Key, give your SSH Key a title, and then paste the output from your previous command into the key section.
7.5 Confirm everything is working with the following command from your Ubuntu terminal:
You should receive the following message:
Hi (username)! You've successfully authenticated, but GitHub does not provide shell access.
Rails is a web application development framework written in Ruby. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started.
8.2 Run the following command with the version you are downloading.
8.3 Confirm your rails version with the following command:
PostgreSQL is a powerful, open-source database system that stores and manages data for applications. It's known for being reliable, secure, and supporting complex queries, making it a popular choice for web apps, analytics, and more. We will be setting up our Ruby on Rails Development Environment to utilize PostgreSQL.
9.1 Install PostgreSQL with the following command:
9.2 Begin the Postgres service with the following command:
9.4 Start PostgreSQL on bootup with the following command:
0.1 Install Redis with the following command:
0.2 Start your Redis server with the following command:
0.3 Enable Redis to start on bootup.
Your Ruby on Rails development environment is almost complete. The last steps are to create your app, create your database, and get coding.
10.1 create your app using the following command:
10.2 Change directories to be in your newly created app with the following command:
10.4 Create a new database with the following command:
10.5 Start your rails server with the following command:
Your Ruby on Rails development environment is now complete! 🎉 You are now ready to begin your Ruby on Rails journey. If you are not sure where to start or are looking for more resources to help you in your coding journey, we have compiled a list of resources below.

2.1 Navigate to the Microsoft Store through the Windows Search console or click . Then, search for Ubuntu LTS.
is a Runtime Version Manager that manages multiple runtime versions within a single tool. We utilize asdf for Ruby on Rails to manage both Ruby and Node.js versions.
is the programming language used to build the framework. It’s known for being easy to read and write, which helps developers work quickly and efficiently. Ruby’s flexibility and simple syntax make it an excellent choice for web development, allowing you to build robust applications with less code. Rails uses Ruby to make web development faster and more intuitive.
is needed in a Ruby on Rails environment to handle front-end JavaScript tasks. While Ruby on Rails manages the backend, Node.js is commonly used to process and bundle JavaScript assets (like React, Vue.js, or Angular components), manage package dependencies with npm (Node Package Manager), and run tools like Webpack or Babel to optimize front-end code.
6.5 Install (javascript package manager)
7.1 Create an account on .
7.4 Copy the previous command's output and paste it into your SSH keys in your GitHub account. SSH keys can be found in .
8.1 Check for the newest version of Rails for your environment .
9.3 for your Postgres database with the following command:
Redis is an open-source, in-memory data store used as a database, cache, and message broker. It is super fast and commonly used to store frequently accessed data, improving the performance of web applications by reducing the need to fetch data from a slower database. You can use Redis for or using .
10.3 (Ruby package manager) provides a consistent environment for Ruby projects by tracking and installing the needed gems and versions. Run the following command:
Your app can now be viewed on or by clicking the address in your terminal.
