Angular 6 StaticInjectorError(平台 : core) No provider for

Question

我有一个 Angular 版本为 4.* 的项目。\*。我试图将项目更新为 6 个 Angular 版本。我修复了编译器在构建产品时告诉我的所有错误。他们有很多。现在项目编译没有错误，但在浏览器中不起作用。现在我卡住了。有人可以帮我解决这个问题吗？
我认为这与延迟加载有某种联系，但我很长一段时间都没有找到解决方案。
添加了可以帮助回答的代码。如果你需要别的东西，告诉我。

错误:

Answer 1

通过进入 angular.json 文件并编辑 production: 对象启用详细输出，以便: "aot": true ， “优化”:false，“buildOptimizer”:false。

这将使您能够以更详细的方式查看完整的错误日志(代码不会被最小化)，因此可能是一个简单的修复。

您导入的某些模块可能会导致错误。
