蓝图CSS compress.rb错误

Question

我想使用Ruby压缩器进行自定义布局，我只是使用与Blueprint捆绑在一起的示例。我安装了捆扎机和ChunkyPNG，这是我得到了什么：

D:\bp\lib>ruby compress.rb -p project1 
C:/Ruby192/lib/ruby/gems/1.9.1/gems/bundler-1.0.14/lib/bundler/spec_set.rb:87:in `block in materialize': Could not find ffi-1.0.8 in any of the sources (Bundler::GemNotFound)

from <internal:lib/rubygems/custom_require>:29:in `require' 
from <internal:lib/rubygems/custom_require>:29:in `require' 
from compress.rb:2:in `<main>' 

我不明白什么是写有一行，任何机会，以使其工作，好吗？ 谢谢

最后约书亚·克莱顿（蓝图的CSS作者）帮我与：http://groups.google.com/group/blueprintcss/browse_thread/thread/c19b41c2f8ea06fc/7cc3f1a0f2031295?show_docid=7cc3f1a0f2031295 的解决方案是使用“捆绑安装--without测试”：相当棘手......

Answer 2

未安装ffi gem。在此命令之后再次尝试bundle install。
