应用程序模块服务声明：

        .,
        .,
        'component name',

    ],
    imports: [

        .,
        .,

    ],
    entryComponents: [
        .,
        ., 
       'component name'
    ],
    providers: [
      .,
      .,
      .,

    ],
    bootstrap: [AppComponent]
})

通常，这意味着未将组件添加到声明部分

{
  imports: [],
  providers: [],
  declarations: ["component name"]
}
