Recent versions of Mac OS X have Ruby and Rails installed by default, but you will need to upgrade to version 2.1.4 of Ruby and version 4.1.7 of Rails. To get started, you will need to install XCode, but note that you will NOT be developing in XCode, you just need to have it installed.

A guide to setting up a Ruby on Rails development environment on Mac OS X 10.14 Mojave with Git, MySQL, and PostgreSQL. Skip to main content. View screencasts by curated topics.

One way to install Ruby and Rails is with the command-line tool rbenv. Using rbenv will provide you with a well-controlled and robust environment for developing your Ruby on Rails applications, allowing you to easily switch the version of Ruby for your entire team when needed.

rbenv provides support for specifying application-specific versions of Ruby, lets you change the global Ruby for each user, and allows you to use an environment variable to override the Ruby version.

In this tutorial, you will use rbenv to install and set up Ruby on Rails on your local macOS machine.

Prerequisites

To follow this tutorial, you will need:

• One computer or virtual machine with macOS installed, with administrative access to that machine and an internet connection. This tutorial has been tested on macOS 10.14 Mojave.
• Node.js installed on your macOS machine, as explained in How to Install Node.js and Create a Local Development Environment on macOS. A few Rails features, such as the Asset Pipeline, depend on a JavaScript Runtime. Node.js provides this functionality.

Step 1 — Installing rbenv

In this step, you will install rbenv and make sure that it starts automatically at boot. To do this on macOS, this tutorial will use the package manager Homebrew.

To download the rbenv package with Homebrew, run the following command:

This will install rbenv and the ruby-build plugin. This plugin adds therbenv install command, which streamlines the installation process for new versions of Ruby.

Next, you’ll add the command eval '$(rbenv init -)' to your ~/.bash_profile file to make rbenv load automatically when you open up the Terminal. To do this, open your .bash_profile in your favorite text editor:

Add the following line to the file:

Save and quit the file.

Next, apply the changes you made to your ~/.bash_profile file to your current shell session:

To verify that rbenv is set up properly, use the type command, which will display more information about the rbenv command:

Your terminal window will display the following:

At this point, you have both rbenv and ruby-build installed on your machine. This will allow you to install Ruby from the command line in the next step.

Step 2 — Installing Ruby

With the ruby-build plugin now installed, you can install any version of Ruby you may need through a single command. In this step, you will choose a version of Ruby, install it on your machine, and then verify the installation.

First, use the -l flag to list all the available versions of Ruby:

The output of that command will be a long list of versions that you can choose to install.

For this tutorial, install Ruby 2.6.3:

Installing Ruby can be a lengthy process, so be prepared for the installation to take some time to complete.

Once it’s done installing, set it as your default version of Ruby with the global sub-command:

Verify that Ruby was properly installed by checking its version number:

Your output will look something like this:

To install and use a different version of Ruby, run the rbenv commands with a different version number, such as rbenv install 2.3.0 and rbenv global 2.3.0.

You now have one version of Ruby installed and have set your default Ruby version. Next, you will set yourself up to work with Ruby packages and libraries, or gems, which will then allow you to install Rails.

Step 3 — Working with Gems

Gems are packages of Ruby libraries and programs that can be distributed throughout the Ruby ecosystem. You use the gem command to manage these gems. In this step, you will configure the gem command to prepare for the Rails installation.

When you install a gem, the installation process generates local documentation. This can add a significant amount of time to each gem’s installation process, so turn off local documentation generation by creating a file called ~/.gemrc which contains a configuration setting to turn off this feature:

With that done, use the gem command to install Bundler, a tool that manages gem dependencies for projects. This is needed for Rails to work correctly:

You’ll see output like this:

You can use the gem env command to learn more about the environment and configuration of gems. To see the location of installed gems, use the home argument, like this:

You’ll see output similar to this:

Now that you have set up and explored your gem workflow, you are free to install Rails.

Step 4 — Installing Rails

To install Rails, use the gem install command along with the -v flag to specify the version. For this tutorial, we will use version 5.2.3:

The gem command installs the gem you specify, as well as every dependency. Rails is a complex web development framework and has many dependencies, so the process will take some time to complete. Eventually you’ll see a message stating that Rails is installed, along with its dependencies:

Note: If you would like to install a different version of Rails, you can list the valid versions of Rails by doing a search, which will output a long list of possible versions. We can then install a specific version, such as 4.2.7:

If you would like to install the latest version of Rails, run the command without a version specified:

rbenv works by creating a directory of shims, or libraries that intercept calls and change or redirect them. In this case, shims point Ruby commands to the files used by the Ruby version that’s currently enabled. Through the rehash sub-command, rbenv maintains shims in that directory to match every Ruby command across every installed version of Ruby on your server. Whenever you install a new version of Ruby or a gem that provides commands, such as Rails, you should use rehash.

To rehash the directory of shims, run the following command:

Verify your installation of Rails by printing its version with this command:

You will see the version of Rails that was installed:

With Rails successfully installed, you can begin testing your Ruby on Rails installation and start to develop web applications. In the next step, you will learn how to update and uninstall rbenv and Ruby.

Step 5 — Updating and Uninstalling rbenv and Ruby

When maintaining projects, it is useful to know how to update and uninstall when the need arises. In this step, you will upgrade rbenv, then uninstall Ruby and rbenv from your machine.

You can upgrade rbenv and ruby-build using Homebrew by running the following command:

If rbenv or ruby-build need to be updated, Homebrew will do it for you automatically. If your set up is already up to date, you will get output similar to the following:

This will ensure that we are using the most up-to-date version of rbenv available.

As you download additional versions of Ruby, you may accumulate more versions than you would like in your ~/.rbenv/versions directory. Using the ruby-build plugin’s uninstall subcommand, you can remove these previous versions.

For example, run the following to uninstall Ruby version 2.1.3:

With the rbenv uninstall command you can clean up old versions of Ruby so that you do not have more installed than you are currently using.

If you’ve decided you no longer want to use rbenv, you can remove it from your system.

To do this, first open your ~/.bash_profile file in your editor:

Find and remove the following line from the file to stop rbenv from starting when you open the Terminal:

Once you have deleted this line, save the file and exit the editor.

Run the following command to apply the changes to your shell:

Next, remove rbenv and all installed Ruby versions with this command:

Finally, remove the rbenv package itself with Homebrew:

Check the rbenv version to make sure that it has been uninstalled:

You will get the following output:

This means that you have successfully removed rbenv from your machine.

Conclusion

In this tutorial you installed Ruby on Rails with rbenv on macOS. From here, you can learn more about coding in Ruby with our How To Code in Ruby series. You can also explore how to use Ruby on Rails with PostgreSQL rather than its default sqlite3 database, which provides more scalability, centralization, and stability for your applications.

Adding Ruby on Rails Support

On Windows

Download and install Ruby + Ruby on Rails

• Download the Ruby + Ruby on Rails package for Windows. The package contains Ruby and all its standard extensions, Gem, and the Ruby on Rails (RoR) framework. It was packaged by Aprelium.
• Install the package contents in a directory of your choice (the default location is C:Ruby).

Creating/deploying a Ruby on Rails (RoR) application

• To create a sample Rails application, open a command line window by selecting Start in Windows, then choose Run.., then type cmd and press the Return key. In the displayed command line window, execute the following sequence of commands (press Return after entering each line):

  C:
  mkdir railstest
  cd railstest
  rails cookbook

  The above commands create a subdirectory called cookbook inside C:railstest. The subdirectory contains the skeleton of a sample Rails application that could be improved later.
• If you have a ready-to-use RoR application, copy it in a directory of your choice on your hard drive. In the rest of the instructions, substitute all occurences of C:railstestcookbook with the actual path of the directory where you have put the RoR application.

Declaring the application in Abyss Web Server

• Stop Abyss Web Server (exit the application) and restart it: this will ensure that Abyss Web Server will get the new environment variables just installed by the Ruby + Ruby on Rails package.
• Run Abyss Web Server and open its console.
• Select the host that will serve the RoR application:
  • If you have Abyss Web Server X2, you can create a new one for that purpose.
  • If you have Abyss Web Server X1, you'll have to use the unique available host.
• Press the Configure button associated with the host you have selected (in the Hosts table).
• Select General.
• Enter C:railstestcookbookpublic in the Documents Path field. If you have used other names or created the RoR application in another directory, locate the public subdirectory in your Rails application and make it your Documents Path.
• Press OK.
• Select Scripting Parameters and press Add in the Interpreters table.
• Set Interface to FastCGI (Local - Pipes).
• Enter C:rubybinrubyw.exe in the Interpreter Path field (or locate rubyw.exe or ruby.exe executables in your Ruby + Ruby on Rails installation directory).
• Enter in the Arguments field:

  'C:railstestcookbookpublicdispatch.fcgi'

  You may have to update the path if you have put your RoR application in a directory other than C:railstestcookbook. But in all the cases, backslashes must be doubled and the file path enclosed between double-quotes.
• Press Add in the Extensions table, enter fcgi in the Extension field, press OK, then press OK a second time.
• Select URL Rewriting, press Add in the URL Rewriting Rules table.
• Enter in the Virtual Path Regular Expression field:

  ^(.*)$

• Press Add in the Conditions table.
• Set Variable to REQUEST_FILENAME, set Operator to Is not a file, and press OK.
• Press Add one more time in the Conditions table.
• Set Variable to REQUEST_FILENAME, set Operator to Is not a directory, and press OK.
• Set If this rule matches to Perform an internal redirection.
• Set Redirect to to:

  /dispatch.fcgi?$1

• Press OK.

Apply the modifications

• Press Restart to restart the server.

Test the application

At that stage, Abyss Web Server should be ready to serve your RoR application. To test it, browse http://127.0.0.1 and click on About your application's environment or browse http://127.0.0.1/rails/info/properties directly.

Learn to program using Ruby on Rails

Now it's probably time to read one of the several Ruby on Rails tutorials available on the Internet to understand how it works and to build your first application.
For example, the tutorial in Rolling with Ruby on Rails by Curt Hibbs is Windows centric and explains how to setup Ruby, MySQL, Rails and how to create a simple application. In our case, skip the Ruby and Rails setup as it's already done and begin reading from A Rails Application's Directory Structure in the second page to learn how to start with Rails programming.

On Mac OS X/macOS

Download and install Locomotive (All-in-one Ruby on Rails package)

• Download Locomotive. The package contains Ruby and all its standard extensions, Gem, and the Ruby on Rails (RoR) framework.
• Open the downloaded DMG package file.
• Drag the Locomotive2 folder from the package and drop it on the Applications folder.

Creating/deploying a Ruby on Rails (RoR) application

• Open the Locomotive2 folder you've just copied inside Applications.
• Double-click on the Locomotive application bundle located inside the Locomotive2 folder to launch it.
• In the Applications menu of Locomotive, select Create New...
• For this example, the name of the application will be cookbook and we'll assume it will be put in the /Sites directory. Fill the Create New.. dialog accordingly and click Create
• Locomotive will generate the skelton of a Ruby on Rails application called inside /Sites/cookbook.
• The new application will also be displayed in Locomtive's main window. That window could be used to control Ruby on Rails applications created with Locomotive. There is also a Run button which can start a simple server written in Ruby to test the application locally.
