我正在尝试使用Angular 6构建一个应用程序,我仍在设置所有内容.但似乎我的应用程序中的依赖注入有问题.

它无法解析任何构造函数参数.他们都导致了Uncaught Error: Can't resolve all parameters for AppComponent: (?)..即使是自定义服务也会导致相同的错误.

版本 (省略了对此不会产生任何影响的依赖项)

app.module.ts

@NgModule({
  declarations: [
    AppComponent

export class AppModule { …

我刚刚将一个应用程序模块迁移为一个可导入的库。

我试图让测试正常工作，就像他们以前一样，但我收到了这个错误：

Error: Can't resolve all parameters for ApplicationModule: (?).

我已经看到了这些可能的解决方案： 错误：无法解析 ApplicationModule 的所有参数：(?)和无法解析 ApplicationModule 的参数：(?)但它们无法解决我的问题。
