Question

Testing my class source code with some require code and I keep getting the following error:

“D:/ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
‘require’:cannot load such file — ./xxx.rb (LoadError) from
D:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in
‘require’ from xxx.rb:1:in ”

Here is the code I’m using to test my code:

require "./proj6colecio.rb.txt"
print " "
guitar = Guitar.new("Stratocaster", "Fender", "Solid Body", 6, "Black")
print "Guitar Name: #{guitar.name}\n"
print "Guitar Brand: #{guitar.brand}\n"
print "Guitar Type: #{guitar.type}\n"
print "Number of Strings: #{guitar.strings}\n"
print "Guitar Color: #{guitar.color}\n"
print guitar, "\n"

Not really educated in ruby on rails errors yet as I’m a student still learning the basics of programming.

Thanks alot for any feedback

# Guitar class with instance variables @name, @brand, @type @strings @color and
# method take_strings.

class Guitar

  # initialize method is called when user invokes Guitar.new.
  def initialize(the_name, the_brand, the_type, the_strings, the_color)
    @name = the_name
    @brand = the_brand
    @type = the_type
    @strings = the_strings
    @color = the_color
  end

  # Define getters
  def name
    return @name
  end

  def brand
    return @brand
  end

  def type
    return @type
  end
  def strings
    return @strings
  end

  def color
    return @color
  end
# define setters

  def strings=(value)
    @strings = value
  end

  def to_s
    return "The Guitar is a #{name} made by #{brand}. It is a #{type} with #{strings} strings and is #{color}."
  end

  def change_color
    @color = "Blue"
  end

end

guitars = [ ]

guitars << Guitar.new("Stratocaster", "Fender", "Solid Body", 6, "Black")
guitars << Guitar.new("Les Paul", "Gibson", "Solid Body", 6, "Yellow")
guitars << Guitar.new("White Falcon", "Gretsch", "Semi-Hollow", 6, "White")

# Print all guitars
guitars.each do |g|
  print g, "\n"
end

#Change color of guitar to blue
guitars.each do |g|
  g.change_color
end

guitars.each do |g|
  print g, "\n"
end
end

Try require_relative:

require_relative "proj6colecio.rb.txt"

Also, you don’t need a .txt file extension for a Ruby script either.
