Question

当我从3.1.1 Rails升级到3.2.8时，看到样式表，图像的路由错误真的很令人沮丧。尝试了“捆绑exec rails服务器”命令，并尝试逐个添加文件中的宝石，也不起作用：（

在链接到rails中的资源时，请始终使用asset_path，asset_url或其中一个依次调用这些函数的辅助函数（image_path，image_url，{{ 1}}，javascript_include_tag）。

在您的情况下，您似乎在应用程序布局中硬编码stylesheet_link_tag。简单地将代码改为

/stylesheets/application.css

它应正确指向<%= stylesheet_link_tag :application %>进行开发，并/assets/application.css进行生产（编译资产时）。

此外，如果你有本地编译的资产（如果/assets/application-<sha1 hash>.css中有任何内容，则情况如此。如果您在本地开发，可能需要public/assets），那么您需要以下内容rm -rf public/assets中的一行：

config/application.rb
