ruby-on-rails-3 - 在生产模式下找不到图像

Question

我已将 Rails 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，一切正常。 但是当我在生产模式下启动它时，所有本地镜像都不会显示

例如:

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

我收到此错误:

您需要将 config/environments/production.rb 中的配置更改为

config.serve_static_assets = false

至

config.serve_static_assets = true
