我正在尝试使用Ruby压缩器进行自定义布局，而我只是使用Blueprint捆绑的示例。我安装了Bundler和ChunkyPNG，这就是我所拥有的：
D:bplib>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 C:/Ruby192/lib/ruby/gems/1.9.1/gems/bundler-1.0.14/lib/bundler/spec_set.rb:81:in `map!'

from D:/bp/lib/blueprint/blueprint.rb:5:in `<top (required)>'
from <internal:lib/rubygems/custom_require>:29:in `require'
from <internal:lib/rubygems/custom_require>:29:in `require'
from compress.rb:2:in `<main>'
我一行字都看不懂，有没有机会让它发挥作用？感谢
ffi-gem未安装。请在此命令bundle install之后重试。
最后Joshua Clayton（Blueprint css作者）帮了我一把：http://groups.google.com/group/blueprintcss/browse_thread/thread/c19b41c2f8ea06fc/7cc3f1a0f2031295?show_docid=7cc3f1a0f2031295解决方案是使用"捆绑安装——无需测试"：相当棘手。。。
