我将 Rails 6 应用程序更新到 Rails 7 并使用 importmaps 和 Leaflet。我正在关注How do I use Leaflet in Rails 7? 。我成功构建了一个新应用程序并且运行良好，但升级我的旧应用程序却无法正常工作。
我错过了什么？或者尝试哪些调试步骤？
终端运行服务器中没有错误，Chrome 中也没有控制台错误。然而，在答案之后的新应用程序中，我看到了
。但在更新后的应用程序中，
在我看来 Controller 没有加载。

最佳答案
让我猜一下，您没有更新 manifest.js。您应该有 app/javascript :
// app/assets/config/manifest.js
//= link_tree ../images
//= link_directory ../stylesheets .css
//= link_tree ../../javascript .js
// ^ this one
//= link_tree ../../../vendor/javascript .js
