如何修复资产后来自gem的资产找不到404：预编译

Question

当我运行rake assets:precompile RAILS_ENV=production时，没有包含宝石使用的资产，我的网站显示了很多这些资产找不到的404。

pnotify.core-4a29894be02cb147dd67c1f609148e95.css:1 Failed to load resource: the server responded with a status of 404 (Not Found)
pnotify.buttons-19d9aeb87c03cfef956313439afad682.css:1 Failed to load resource: the server responded with a status of 404 (Not Found)
pnotify.history-d339b3266d96cddfa55c4f0478f9d0ea.css:1 Failed to load resource: the server responded with a status of 404 (Not Found)

生产中的Rails.application.config.assets.paths显示：

任何帮助都将受到欢迎！

问题是config.assets.debug选项，它是生产服务器上的true，而且在CDN中没有文件。

很简单。
