Gosu Installation Error

I'm trying to set up the Ruby for kids tutorial, and am completely stuck on the first step. Something with my GOSU GEM instalation is wring. Whenever I try and run the main file as requested I get this error:

internal:lib/rubygems/custom_require:29:in require': no such file to load -- gosu (LoadError) from internal:lib/rubygems/custom_require>:29:in require'

from main.rb:1:in `main'

I have run the $ sudo gem install gosu many times in different locations, upon studying the outcome I've located this:

ERROR:  Error installing gosu:

ERROR: Failed to build gem native extension.

/Users/carlosamengual/.rvm/rubies/ruby-1.9.2-p320/bin/ruby extconf.rb

The Gosu gem requires some libraries to be installed system-wide. See the following site for a list: https://github.com/jlnr/gosu/wiki/Getting-Started-on-Linux

I'm assuming I'm doing something wrong. I've visited the site it says, but I believe, since it is a ruby project I don't need anything else? Can anyone advise as to how to fix it?

Be sure you using rbenv or install ruby by homebrew. Rvm is not compatible with gosu. Install homebrew: https://brew.sh/ .

Then:

brew install sdl2
brew install libogg libvorbis
brew unlink imagemagick
brew install imagemagick@6 && brew link imagemagick@6 --force

And have fun!

If you are using Ruby Gosu on OSX, you might want to go here:

https://github.com/gosu/gosu/wiki/Getting-Started-on-OS-X

For what it is worth, I'm currently using Ubuntu 14 with Ruby 2.3 and using rvm 1.11.3.9 I have downloaded gosu 0.10.8 and successfully gotten a gosu window to load. I had the same problem while starting off with Ruby Gosu and using "bundler" in the project directory took care of the gem dependency. In addition to visiting this website:

https://github.com/gosu/gosu/wiki/Getting-Started-on-Linux

and after entering this in the command line: 

user@ubuntu:~/Ruby/gosu_project$ sudo apt-get install build-essential libsdl2-dev libsdl2-ttf-dev libpango1.0-dev libgl1-mesa-dev libfreeimage-dev libopenal-dev libsndfile-dev


user@ubuntu:~/Ruby/gosu_project$ gem install gosu

I also had to invoke:

user@ubuntu:~/Ruby/gosu_project$bundle

http://bundler.io/ - also works with MacOSX...

per: https://github.com/gosu/gosu/wiki/ruby-tutorial

This gosu file:

# basic Gosu: gui test file

require 'gosu'
require_relative 'gosu_test.rb'

class TestWindow < Gosu::Window   # <-- inherits from Gosu Window Super class

  def initialize
    super 640, 480, false         # <-- width, height, fullscreen = false
    self.caption = "successful gosu test window"
  end

  def update
  end

  def draw
  end

end


TestWindow.new.show

...loads a 640x480 window

user@ubuntu:~/Ruby/gosu_project$ ruby gosu_test.rb

I had similar issue whilst installing on OS X 10.9.4 although am not sure the version has much to do with it, but ruby version is ruby-2.1.2

To resolve this, I installed these additional dependencies for Gosu which fixed the problem:

brew install sdl2 libogg libvorbis

Then run gem install gosu as usual.
