CF 总会出现些古怪的问题，话说不但 gem 部署有问题，部署好了使用也有问题 bundle package 一下 然后重新 vmc push app --runtime ruby19 试下

我尝试了一下，现在换了一个错，

看样子好象不能安装 libv8

这个问题好像碰到过，试下 gem 'cloudfoundry-jquery-rails' gem 'cloudfoundry-devise', :require => 'devise' gem 'json' gem 'thin'

cloud_controller 和你的项目是用 thin 跑的

我在 gem 中加了这三个，貌似启动的时候还是报同样的错？看起来是 therubyracer-0.10.1.gem 这个安装的时候依赖 libv8，而 libv8 没有安装？ 我没有显示的 gem libv8 的？

可以去掉 therubyrace 试下，你看 vendor/cache 里有没有 libv8，你可以先尝试跑一个空的 rails 应用试试，可以 gtalk 我，[email protected]

cloudfoundry 就不支持 libv8
