How to Install Omnibus-Ruby on macOS

Omnibus-Ruby is a packaging system that allows you to create stand-alone, platform-specific packages of Ruby applications for easy installation on any system. In this tutorial, we’ll cover how to install Omnibus-Ruby on macOS.

Prerequisites

Before beginning, ensure that you have the following:

• A macOS machine running version 10.9 or later
• Xcode command line tools installed
• Homebrew package manager installed

Installation Steps

1. Install the latest version of Ruby using Homebrew. Open the Terminal app and enter the following command:

   brew install ruby
   

2. Install the bundler gem by running the following command:

   gem install bundler
   

3. Clone the Omnibus-Ruby repository from GitHub:

   git clone git://github.com/chef/omnibus.git
   

4. Change your current directory to the cloned Omnibus-Ruby repository:

   cd omnibus
   

5. Run the bundler to install all necessary gems:

   bundle install
   

6. Now you’re ready to build the Omnibus-Ruby gem. Run the following command:

   bundle exec rake gem
   

   This will package the Omnibus-Ruby gem as pkg/omnibus-x.y.z.gem, where x.y.z is the version number.

7. Install the Omnibus-Ruby gem using the following command:

   gem install pkg/omnibus-x.y.z.gem
   

8. Verify that the Omnibus-Ruby installation was successful by running the following command:

   omnibus --version
   

   This will display the installed version number of Omnibus-Ruby.

That’s it! You now have Omnibus-Ruby installed on your macOS machine. You can use it to create and package Ruby applications as stand-alone, platform-specific packages for easy installation on any system.
