Question

我已将rails的应用程序升级到rails版本3。当我在开发模式下启动应用程序时，所有工作。但是当我在生产模式下启动时，所有本地图像都没有显示

例如：

http://localhost:3000/images/background.jpg

我收到此错误：

为什么？

我该如何解决？

感谢

Answer 1

您需要更改config/environments/production.rb中的配置

config.serve_static_assets = false

到

config.serve_static_assets = true

Answer 2

您也可以尝试这样做： config.assets.compile = true

生产模式中找不到图像
