Gosu Installation Error

Question

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?

Answer 1

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.
