Ruby on rails rails:application.css加载资源失败：服务器响应状态为404（未找到）

我给heroku推了一些代码，我的应用程序坏了。 我在浏览器控制台中遇到以下错误：

未能加载资源：服务器以404状态响应 （未找到）2 未能加载资源：服务器以404状态响应 （未找到）

这是今天第二次发生。首先，我将新代码推送到服务器上，它就开始工作了。但现在我开始担心是否出了什么问题。 在本地，它运行良好

My application.js file

// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,

// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the

My application.css文件

/*

 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the

更改

config.assets.compile=true

在config/environments/production.rb

中，确保使用rails帮助程序获取资产路径：不要在代码中硬编码“/assets/name.extension”路径，Heroku将为您编译资产，它们的最终路径更像：/assets/application-6aae32862efc758cf08c7b7fc0e85e15.js

简单地使用

和

助手方法应该适合您

如果您仍有问题，请按照Heroku帮助中的调试部分进行操作：

特别是：

$ heroku run rails console
> puts helper.asset_path("application.js")
/assets/application-6aae32862efc758cf08c7b7fc0e85e15.js

你能告诉我们你是如何在你的html中包含这些内容的吗<代码>？Heroku不需要这些，请参阅此处的官方文档：
