我尝试了我所知道的一切来预编译所有 css 和 js 文件，但仍然收到我什至设置config.assets.precompile += ['*.js', '*.css']但仍然无法正常工作的这个错误。当我转向config.serve_static_assets一切true工作时，但如您所知，它有一些缺点！有什么线索吗？

看起来您正在尝试直接加载脚手架 css 文件 - application.html.erb 的第 7 行？我不熟悉您所依据的教程，但通常您的stylesheet_link_tagisapplication本身就是一个清单文件，让 sprockets 知道需要编译什么。

在您的 assets\stylesheets 目录中创建一个application.css文件，它应该如下所示；

/*
*= require_self
*= require_tree
*/

您可以保留现有的 scaffold.css 文件，因为 require_tree 将使 sprockets 在其编译任务中包含该文件。
