Dart web教程问题重新生成app组件

Question

我正在尝试在 https://webdev.dartlang.org/angular/tutorial/toh-pt5 处学习 Dart Web 教程

为了确保从正确的基础开始，我下载了上一章末尾的模板 toh-4-master。它构建并运行良好，然后我按照指南移动和重命名应用程序组件，然后创建手动新建一个，但是在遵循“创建应用程序组件”之后，指南指出重新加载页面并且应用程序应该可以工作，但是我收到了下面的错误。

这表明它没有正确生成 app_component.template 文件，知道如何调试它吗？

Unable to find modules for some sources, this is usually the result of either a
bad import, a missing dependency in a package (or possibly a dev_dependency
needs to move to a real dependency), or a build failure (if importing a
generated file).

您是否也重命名了组件文件？

如果是这样，则从包含组件的文件生成 template.dart 文件。所以它将遵循模式 component.dart -> component.template.dart
