OS X error: 'no such file to load'

By ? Date 2010-11-22 10:14

Surely I'm overlooking something trivial?
I'll go step by step...

I'm running OS X -v 10.6.5

$ ruby -v
version is: ruby 1.8.7 (2009-06-12 patchlevel 174) [i686-darwin9.7.0]

$ which ruby
/usr/local/bin/ruby

$ gem -v
1.3.7

$ which gem
/usr/local/bin/gem

$ sudo gem install gosu

$ gem which gosu
/usr/local/lib/ruby/gems/1.8/gems/gosu-0.7.25-universal-darwin/lib/gosu.rb

I create gosutest.rb with the following:

require 'rubygems' # Remove this line if you aren't using RubyGems
require 'gosu'

class MyWindow < Gosu::Window
def initialize
super(640, 480, false)
self.caption = 'Hello World!'
end
end

w = MyWindow.new
w.show

$ ruby gosutest.rb

/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in

gem_original_require': no such file to load -- /usr/local/lib/ruby/gems/1.8/gems/gosu-0.7.25-universal-darwin/lib/gosu.bundle (LoadError)

What am I missing here?

Also, I've tried running Tutorial.rb in the examples directory with the same error.

Gosu tries to load "gosu.bundle" (which you shouldn't have) if loading "gosu.for_1_8.bundle" fails. See lib/gosu.rb:


  require "#{File.dirname(__FILE__)}/gosu.for_#{version}.#{Config::CONFIG['DLEXT']}"
  require "#{File.dirname(__FILE__)}/gosu/swig_patches.rb"
rescue LoadError => e
  require "#{File.dirname(__FILE__)}/gosu.#{Config::CONFIG['DLEXT']}"
  require "#{File.dirname(__FILE__)}/gosu/swig_patches.rb"

If you comment the whole rescue portion out, you should get the original exception. Can you post its message? (I should really change that part in gosu.rb)

Thanks for the quick reply, Julian! As it turns out, my Ruby.framework is missing...

I commented out the rescue block like so:

require 'rbconfig'

begin
  if defined? RUBY_VERSION and RUBY_VERSION[0..2] == '1.9' then
    version = '1_9'
  else
    version = '1_8'
  end
  require "#{File.dirname(__FILE__)}/gosu.for_#{version}.#{Config::CONFIG['DLEXT']}"
  require "#{File.dirname(__FILE__)}/gosu/swig_patches.rb"
#rescue LoadError => e
#  require "#{File.dirname(__FILE__)}/gosu.#{Config::CONFIG['DLEXT']}"
#  require "#{File.dirname(__FILE__)}/gosu/swig_patches.rb"
end

require "#{File.dirname(__FILE__)}/gosu/patches.rb"

And get the following error:

/usr/local/lib/ruby/gems/1.8/gems/gosu-0.7.25-universal-darwin/lib/gosu.for_1_8.bundle: dlopen(/usr/local/lib/ruby/gems/1.8/gems/gosu-0.7.25-universal-darwin/lib/gosu.for_1_8.bundle, 9): Library not loaded: /usr/lib/libruby.1.dylib (LoadError)

Here is the contents of my /usr/local/lib/ruby/gems/1.8/gems/gosu-0.7.25-universal-darwin/lib directory:

gosu      
gosu.for_1_8.bundle  
gosu.for_1_9.bundle  
gosu.rb

So yeah, no gosu.bundle.

I looked for /usr/lib/libruby.1.dylib and saw that it was a broken alias. After some further investigation I learned that it should point to ../../System/Library/Frameworks/Ruby.framework/Versions/Current/usr/lib/libruby.1.dylib. Somehow, I'm not sure how or why, my /System/Library/Frameworks/Ruby.framework doesn't exist. I'll correct this.

Thanks for the help in hunting this down.
