Cannot load RubyCocoa library

[Deleted user]

Cannot load RubyCocoa library
wkpdf requires that RubyCocoa is installed, which is shipped by default since
Mac OS X 10.5. If you use Mac OS X 10.4, you have to install RubyCocoa
yourself from http://rubycocoa.sourceforge.net/HomePage

I'm on OSX 10.8.2 using rvm installed it to global ruby1.9.3-P194

[Christian Plessl]

Sorry, but I cannot provide any help with that. I have no experience with a manual installation of RubyCocoa. Since OS X has started to bundle RubyCocoa there is no need to install it by hand anymore.

[Deleted user]

But shouldn't it be able to find the installed bundle ?

Yes, it should. This is why this looks more like a RubyCocoa problem than a wkpdf problem to me.

Are you able to run one of the sample scripts shipped with RubyCocoa?

What happens for example if you save the following script (from the RubyCocoa examples) to a file fontnames.rb and run it with ruby fontnames.rb?

require 'osx/cocoa'

fmgr = OSX::NSFontManager.sharedFontManager

puts "## all fonts ##"
fonts = fmgr.availableFonts.to_a.map{|i| i.to_s }
fonts.each {|i| puts i }

puts "## fixed pitch fonts ##"
fixedfonts =
  fmgr.availableFontNamesWithTraits(OSX::NSFixedPitchFontMask).to_a
fixedfonts.each {|i| puts i.to_s }

Sorry to bother you with this but I'm quite new to Ruby

As I suspected, it looks like RubyCocoa is not properly installed in your rvm setup.

Maybe this is of help:

[Deleted user]

Thank you for looking into this. I'll try that suggestion

Kind regards,

Unfortunately I have no idea what the problem could be. But for what reason do you want to use rvm? RubyCocoa and wkpdf work just fine with the default Ruby installation shipped with OS X 10.7 and 10.8, probably also 10.6.

Actually I don't know how to switch to the default Ruby installation, without removing rvm?

I don't have any idea. A quick google search pointed out bundler, rubygems of rvm as possible sources for this error. But debugging this is beyond the support I can offer.

No problem, I won't take up more of your time, you have been very helpful. I came across that same thing via google but couldn't make head or tails from it. I'll uninstall rvm eventually and see if that helps.

@Stofke72 I had the same issue. Try this:

• Uninstall the gem: sudo gem uninstall wkpdf
• Reinstall using the non-rvm gem: sudo /usr/bin/gem install wkpdf

[nickcheng]

@mastahyeti Thanks. It works.

[Deleted user]

I had the same problem. I have OS X 10.8.3

Cannot load RubyCocoa library
wkpdf requires that RubyCocoa is installed, which is shipped by default since
Mac OS X 10.5. If you use Mac OS X 10.4, you have to install RubyCocoa
yourself from http://rubycocoa.sourceforge.net/HomePage

So I followed mastahyeti,

Uninstall the gem: sudo gem uninstall wkpdf
Reinstall using the non-rvm gem: sudo /usr/bin/gem install wkpdf

But I get an error as following. Anyone knows how to fix it? Thank you in advance.

[Christian Plessl]

Is rvm really deactivated for your environment?

Is /usr/bin/gem a symlink and where does it point to (ls -l /usr/bin/gem)?

On my installation it points to: ../../System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/gem

[Christian Plessl]

Using wkpdf with non-default Ruby installations is not supported.
