尝试按照https://github.com/documentcloud/documentcloud/blob/master/INSTALL上的说明安装 documentcloud 。Nginx 启动正常，但出现错误：
no such file to load -- bundler/setup (LoadError)
/usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require'
/usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:36:in `require'

/root/.gems/gems/passenger-4.0.4/helper-scripts/rack-preloader.rb:127
不知道除了我的配置之外还包括什么：
