How to use require in Ruby?

Question

I'm having trouble using the require in Ruby when I try to call the animal object.

#Classe Animal in file call animal.rb
class Animal
    def pular
        puts 'Toing! tóim! bóim! póim!'
    end

    def dormir
        puts 'ZzZzZ!'
    end
end


# Require rying to call the class Animal with arquivo app.rb
require './animal.rb'

animal = Animal.new

animal.pular

Traceback (most recent call last):
app.rb:3:in '': uninitialized constant Animal (NameError)

ok. my question is: I'm having trouble using the require in Ruby when I try to call the animal object. — Jacob Rodrigues

You don't specify the ".rb" as Ruby will search for matching ".rb" (or ".dll" or whatever)

Also the file is in the same directory, so you would use require_relative

require_relative 'animal'
