请检查您的开发控制台.它给出了一个错误

EXCEPTION:在实现LocationStrategy期间出错!(RouterLink - >路由器 - >位置 - > LocationStrategy).BrowserDomAdapter.logError @ angular2.dev.js:23514个angular2.dev.js:23514原始异常:无基本href集.请提供APP_BASE_HREF标记的值或向文档添加基本元素.

此外,它不会将我重定向到目的地.我试图添加<base href ="/">但它允许给出错误.

我希望链接正常工作.

无论是添加<base href="/">到<head>元素或添加APP_BASE_HREF到引导

bootstrap(AppComponent, [
  ROUTER_PROVIDERS, 
  // usually
  provide(APP_BASE_HREF, {useValue: '/'})
  // for Plunker
  // bind(APP_BASE_HREF).toValue(location.pathname)
]);

答案由Nyks编辑:

在我的plunker中,我更新了以下部件,

import {Component,bind} from 'angular2/core';
import {ROUTER_PROVIDERS,RouteConfig, ROUTER_DIRECTIVES,APP_BASE_HREF,LocationStrategy,RouteParams,ROUTER_BINDINGS} from 'angular2/router';

export class AppComponent { }

    bootstrap(AppComponent, [
      ROUTER_PROVIDERS,bind(APP_BASE_HREF).toValue(location.pathname)
]);
