To develop a web application using Ruby on Rails Framework, you need to install the following software −

  • Ruby
  • The Rails Framework
  • A Web Server
  • A Database System
Download Rails Mac

We will be setting up a Ruby on Rails development environment on Mac OS X 10.10 Yosemite. Older versions of OS X are mostly compatible so follow along as far as you can and then Google search for any problems you run into. There are plenty of people who have documented solutions for them. Install Ruby on Rails Mac. With Ruby 3.0 and Rails 6.1. Up-to-date guide from the author of the book, Learn Ruby on Rails. For macOS Big Sur or Catalina. As one of the most powerful ways to quickly develop web applications, Ruby on Rails has a high relevance and demand in today’s marketplace. Codecademy Team M.

We assume that you already have installed a Web Server and a Database System on your computer. You can use the WEBrick Web Server, which comes with Ruby. Most websites however use Apache or lightTPD web servers in production.

Rails works with many database systems, including MySQL, PostgreSQL, SQLite, Oracle, DB2 and SQL Server. Please refer to a corresponding Database System Setup manual to set up your database.

Let's look at the installation instructions for Rails on Windows and Linux.

Rails Installation on Windows

Follow the steps given below for installing Ruby on Rails.

Step 1: Check Ruby Version

First, check if you already have Ruby installed. Open the command prompt and type ruby -v. If Ruby responds, and if it shows a version number at or above 2.2.2, then type gem --version. If you don't get an error, skip Install Ruby step. Otherwise, we'll install a fresh Ruby.

Step 2: Install Ruby

Download Rails Mac

If Ruby is not installed, then download an installation package from rubyinstaller.org. Follow the download link, and run the resulting installer. This is an exe file rubyinstaller-2.2.2.x.exe and will be installed in a single click. It's a very small package, and you'll get RubyGems as well along with this package. Please check the Release Notes for more detail.

Step 3: Install Rails

Install Rails − With Rubygems loaded, you can install all of Rails and its dependencies using the following command through the command line −

Note − The above command may take some time to install all dependencies. Make sure you are connected to the internet while installing gems dependencies.

Step 4: Check Rails Version

Use the following command to check the rails version.

Output

Congratulations! You are now on Rails over Windows.

Rails Installation on Linux

We are installing Ruby On Rails on Linux using rbenv. It is a lightweight Ruby Version Management Tool. The rbenv provides an easy installation procedure to manage various versions of Ruby, and a solid environment for developing Ruby on Rails applications.

Follow the steps given below to install Ruby on Rails using rbenv tool.

Step 1: Install Prerequisite Dependencies

First of all, we have to install git - core and some ruby dependences that help to install Ruby on Rails. Use the following command for installing Rails dependencies using yum.

Step 2: Install rbenv

Now we will install rbenv and set the appropriate environment variables. Use the following set of commands to get rbenv for git repository.

Step 3: Install Ruby

Before installing Ruby, determine which version of Ruby you want to install. We will install Ruby 2.2.3. Use the following command for installing Ruby.

Use the following command for setting up the current Ruby version as default.

Use the following command to verify the Ruby version.

Output

Download Rails Mac Version

Ruby provides a keyword gem for installing the supported dependencies; we call them gems. If you don't want to install the documentation for Ruby-gems, then use the following command.

Thereafter, it is better to install the Bundler gem, because it helps to manage your application dependencies. Use the following command to install bundler gem.

Step 4: Install Rails

Use the following command for installing Rails version 4.2.4.

Use the following command to make Rails executable available.

Use the following command for checking the rails version.

Output

Ruby on Rails framework requires JavaScript Runtime Environment (Node.js) to manage the features of Rails. Next, we will see how we can use Node.js to manage Asset Pipeline which is a Rails feature.

Step 5: Install JavaScript Runtime

Let us install Node.js from the Yum repository. We will take Node.js from EPEL yum repository. Use the following command to add the EPEL package to the yum repository.

Use the following command for installing the Node.js package.

Congratulations! You are now on Rails over Linux.

Step 6: Install Database

By default, Rails uses sqlite3, but you may want to install MySQL, PostgreSQL, or other RDBMS. This is optional; if you have the database installed, then you may skip this step and it is not mandatory that you have a database installed to start the rails server. For this tutorial, we are using PostgreSQL database. Therefore use the following commands to install PostgreSQL.

Accept the prompt, by responding with a y. Use the following command to create a PostgreSQl database cluster.

Use the following command to start and enable PostgreSQL.

Keeping Rails Up-to-Date

Assuming you have installed Rails using RubyGems, keeping it up-to-date is relatively easy. We can use the same command in both Windows and Linux platform. Use the following command −

Output

Ruby On Rails Lessons

The following screenshot shows a Windows command prompt. The Linux terminal also provides the same output.

This will automatically update your Rails installation. The next time you restart your application, it will pick up this latest version of Rails. While using this command, make sure you are connected to the internet.

Installation Verification

You can verify if everything is set up according to your requirements or not. Use the following command to create a demo project.

Output

It will generate a demo rail project; we will discuss about it later. Currently we have to check if the environment is set up or not. Next, use the following command to run WEBrick web server on your machine.

It will generate auto-code to start the server

Now open your browser and type the following −

Ruby On Rails Mac

It should display a message, something like, 'Welcome aboard' or 'Congratulations'.
