ruby-on-rails - 生产中未找到 Rails 4 Assets (摘要路径没问题)

Question

我在生产中遇到 Assets 问题。

我无法加载样式表、javascripts 甚至图像。

当我尝试访问某些内容时，它显示错误 - 未找到
但是当我尝试使用 -digest 访问时，就可以了。

我有 Assets 预编译，通过 capistrano 与 manifest -> assets_manifest.json 成功部署

谢谢

日志:样式表错误(使用 themes_for_rails gem 加载样式表)
当我尝试访问/assets/default/stylesheets/application-ec9a310f792c60f2f77810cfcd9b903f.css 时，一切正常

您可能遇到与此处所述相同的问题:No route matches [GET] /assets

基本上，如果您使用 rails 服务器来测试您的应用程序，则默认情况下不会提供您的预编译 Assets 。 Rails 期望 Web 服务器(apache、nginx 等)为它们提供服务。您需要更改 config/environments/production.rb 并将 serve_static_assets 设置为 true。
