我遗漏了什么？或者尝试哪些调试步骤？

终端运行服务器没有错误，Chrome没有控制台错误。然而，在这个新的应用程序中，我看到了

。但在更新的应用程序中，

在我看来控制器没上膛。

让我猜猜，你没有更新manifest.js。您应该在那里有app/javascript：

// app/assets/config/manifest.js

//= link_directory ../stylesheets .css
//= link_tree ../../javascript .js
//  ^ this one
//= link_tree ../../../vendor/javascript .js
