How to find a module's location

To find a module's location in Ruby, you can follow these steps:

1. Use the require method to load the module into your script. For example, if you want to find the location of the json module, you can use require "json".

2. Once the module is loaded, you can use the method method on the module object to retrieve the path of the module file. For example, if you want to find the location of the json module, you can use puts method(:json).source_location.

3. The source_location method will return an array containing the path to the module's file and the line number where the module is defined.

4. You can use the File.expand_path method to get the absolute path of the module file. For example, if the module file path is relative, you can use File.expand_path(path) to get the absolute path.

By following these steps, you can find the location of a module in Ruby.
