Ruby on rails Rails 3.1.1资产预编译-rake中止

编辑：其他人有什么建议吗？我完全被难住了

我有一个应用程序，其中所有资产都可以正常编译，但在第二个应用程序中，当我运行时：

RAILS_ENV=production rake assets:precompile --trace

我收到以下消息：未定义nil:NilClass的方法'directory'

请帮忙。当我在public/assets目录下查看时，我看到图像文件已经预编译，但是没有js或css文件

以下是完整的终端输出：

=> RAILS_ENV=production rake assets:precompile --trace
