To install a Ruby application in cPanel, you will need to follow these steps:
-
Login to your cPanel account.
-
In the "Software" section, click on the "Select Ruby Version" icon.
-
Choose the version of Ruby that you want to use for your application and click "Set as Current".
-
In the "Software" section, click on the "Ruby Gems" icon.
-
In the "Install a Gem" section, enter the name of the gem you want to install and click "Install".
-
Once the installation is complete, you can use the gem by typing "gem list" to see a list of all installed gems, or "gem which gemname" to see the location of a specific gem.
-
To use a gem in your Ruby application, you will need to require it at the top of your Ruby file, like this:
require 'gemname'
You can then use the functions and methods provided by the gem in your code.
Note: If you want to install a Ruby application that has multiple dependencies, you may need to install additional gems. You can do this by repeating steps 4 and 5 for each gem that you need.
