We deprecated this interface in cPanel & WHM version 66. To create a Ruby application in cPanel & WHM version 66 and later, perform the following steps:

  1. Ask your hosting provider to install Ruby on your system via the following EasyApache 4 RPMs:
    • The ea-apache24-mod_env module.

    • The ea-ruby24-ruby-devel module.

  2. Create a Ruby application on your server. For an example of how to do this, read our How to Create Ruby Web Applications documentation.
  3. Use cPanel's Application Manager interface (cPanel >> Home >> Software >> Application Manager) to register the application.

RubyGems is a package manager for the Ruby programming language. It provides a self-contained format in which developers can distribute Ruby programs and libraries.
