.rb: 2: in 'read': No such file or directory @ rb_sysopen - GameSettings.json (Errno :: ENOENT)

I'm trying to make a game in ruby using gosu , and to be able to change the name of the game without having to change all the variables related to name in my code and other things, I decided to use .json . Here is the script code ruby :

require 'gosu'
require 'json'

data_hash = JSON.parse(File.read('GameSettings.json'))

largura = 360
altura = 360
class GameWindow < Gosu::Window
    def initialize(width , height , fullscreen = false)
        super
        self.caption = data_hash['name']
        @message = Gosu::Image.from_text(self, data_hash['Author'], Gosu.default_font_name,30)
    end
    def draw
       @message.draw(10,10,0)
    end
end

window = GameWindow.new(largura, altura, false)
window.show

and GameSettings.json:

{
    "name"  :   "Heart Afeathered",
    "Author"    :   "Davi Martins Guedes",
    "Nacionality"   : "Brazil"
}

And when I run that message I put it in the title.

The GameSettings.json file is apparently not in the same folder as the .rb file. Try to pass the full path to the file, as in the example:

_ jogo (pasta)
    _ config (pasta)
        GameSettings.json (arquivo)
    Jogo.rb (arquivo)

data_hash = JSON.parse(File.read('config/GameSettings.json'))

In addition, the initialize function of the GameWindow object will not be able to read the data_hash variable because it is in a different scopes, so it is necessary that data_hash be initialized within GameWindow initialize function.
