Angular2异常:无法绑定到’routerLink’,因为它不是一个已知的
显然,Angular2的beta比新的更新,所以没有太多的信息,但我试图做我认为是一些相当基本的路由。
使用快速启动代码和来自https://angular.io网站的其他片段进行攻击,导致了以下文件结构: angular-testapp/ app/ app.component.ts boot.ts routing-test.component.ts index.html 随着文件被填充如下: index.html <html> <head> <base href="/"> <title>Angular 2 QuickStart</title> <link href="../css/bootstrap.css" rel="stylesheet"> <!-- 1. Load libraries --> <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script> <script src="node_modules/systemjs/dist/system.src.js"></script> <script src="node_modules/rxjs/bundles/Rx.js"></script> <script src="node_modules/angular2/bundles/angular2.dev.js"></script> <script src="node_modules/angular2/bundles/router.dev.js"></script> <!-- 2.

Display the application --> <body> <my-app>Loading...</my-app> </body> </html> boot.ts import {bootstrap} from 'angular2/platform/browser' import {ROUTER_PROVIDERS} from 'angular2/router'; import {AppComponent} from './app.component' bootstrap(AppComponent,[ ROUTER_PROVIDERS ]); app.component.ts import {Component} from 'angular2/core'; import {RouteConfig,ROUTER_DIRECTIVES,ROUTER_PROVIDERS,LocationStrategy,HashLocationStrategy} from 'angular2/router'; import {RoutingTestComponent} from './routing-test.component'; @Component({ selector: 'my-app',template: ` <h1>Component Router</h1> <a [routerLink]="['RoutingTest']">Routing Test</a> <router-outlet></router-outlet> ` }) @RouteConfig([ {path:'/routing-test',name: 'RoutingTest',component: RoutingTestComponent,useAsDefault: true},]) export class AppComponent { } routing-test.component.ts import {Component} from 'angular2/core'; import {Router} from 'angular2/router'; @Component({ template: ` <h2>Routing Test</h2> <p>Interesting stuff goes here!</p> ` }) export class RoutingTestComponent { } 尝试运行此代码会产生错误: EXCEPTION: Template parse errors: Can't bind to 'routerLink' since it isn't a known native property (" <h1>Component Router</h1> <a [ERROR ->][routerLink]="['RoutingTest']">Routing Test</a> <router-outlet></router-outlet> "): AppComponent@2:11 我在这里发现了一个模糊的相关问题; router-link directives broken after upgrading to angular2.0.0-beta.0.然而,答案之一的“工作示例”基于预beta代码 – 这仍然可以工作,但我想知道为什么我创建的代码不工作。 任何指针都会感谢!
