after updating my project to RC6 following errors occurs:Error: Typescript found the following errors: app.component.ts (12, 3): Argument of type '{ moduleId: string; selector: string; templateUrl: string; styleUrls: string[]; directives: (type...' is not assignable to parameter of type 'ComponentMetadataType'. Object literal may only specify known properties, and 'directives' does not exist in type 'ComponentMetadataType'.app.component.tsimport {Component, OnInit} from '@angular/core';import {NavbarComponent} from "./shared/navbar/navbar.component";import {ROUTER_DIRECTIVES} from "@angular/router";import {SidebarComponent} from "./shared/sidebar/sidebar.component";import {FooterComponent} from "./shared/footer/footer.component";@Component({ moduleId: module.id, selector: 'app-root', templateUrl: 'app.component.html', styleUrls: ['app.component.css'], directives: [NavbarComponent, SidebarComponent, FooterComponent, ROUTER_DIRECTIVES]})export class AppComponent implements OnInit { ngOnInit(): any { return undefined; }}It take my a while, but I cant figure it out. 解决方案 Directives and pipes must be defined in @NgModule If I'm reading correctly. Support inside @Component is removed.So yeah just move your directives into the NgModuleAt the moment you have : Component A with directives Ac and Component B with directives Bc and most likely one AppModule, you just have to move Ac and Bc into the AppModule. And yes, you have to remove them from the @Component declarationThe directives will then be immediately available in the components that are defined in your module.Example from OP becomes:app.component.ts// imports...@Component({ selector: 'app-root', templateUrl: 'app.component.html',})export class AppComponent {}app.module.ts// imports...@NgModule({ declarations: [ AppComponent, NavbarComponent, SidebarComponent, FooterComponent ], imports: [ BrowserModule, CommonModule, FormsModule ], providers: [ //MyService, MyOtherService ], entryComponents: [AppComponent], bootstrap: [AppComponent]})export class AppModule {}See the doc for router: router documentation 这篇关于Angular2 RC6升级的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
