红宝石：没有这样的文件加载 - 咖啡/铁轨

Question

我是一个红宝石新手。我创建了我的第一个ruby on rails应用程序，在我的mac上命名为“HelloRubyWeb”。然后是“cd HelloRuby”，但是当我输入命令“rails s”，它返回错误日志：

/Library/Ruby/Gems/1.8/gems/bundler-1.1.5/lib/bundler/runtime.rb:74:in `require': no such file to load -- coffee/rails (LoadError)

from /Library/Ruby/Gems/1.8/gems/railties-3.2.7/lib/rails/commands.rb:50 
from script/rails:6:in `require'

任何人都可以帮助我吗？很感谢。

kasperite可能是正确的，在终端运行：

bundle然后运行rails s

后你得到的错误，如果有的话。
