我正在使用打字稿编写一个 angular2-meteor 应用程序。

angular2-meteor 0.5.5 现在支持 angular 2.0.0-rc1

这是我更新的 app.ts

import 'reflect-metadata';
import 'zone.js/dist/zone';
import {Component,provide} from '@angular/core';
import {APP_BASE_HREF} from '@angular/common';
import {bootstrap} from 'angular2-meteor-auto-bootstrap';
import {ROUTER_PROVIDERS, ROUTER_DIRECTIVES, Routes} from '@angular/router';

import {MdToolbar} from '@angular2-material/toolbar';
import {MdButton} from '@angular2-material/button';
import {Welcome} from './imports/pages/welcome/welcome';
import {AddDrink} from './imports/pages/add-drink/add-drink';

@Component({
 selector: 'app',
 templateUrl: 'client/app.html',
 directives: [MdToolbar,MdButton,ROUTER_DIRECTIVES],
 providers: [ROUTER_PROVIDERS,provide(APP_BASE_HREF, { useValue: '/' })]
})
@Routes([
 { path: '/', component: Welcome },
 {path: '/add-drink',component:AddDrink}  
])
class MyAlcoholist { }

bootstrap(MyAlcoholist);

这是我的主要 index.html 文件：

<body>
 <app></app>
</body>

这是主要的组件 html 文件：

<md-toolbar [color]="primary">
 <span>MyAlcoholist</span>&nbsp;
 <button md-raised-button color="primary">Home</button>&nbsp;
 <button md-raised-button color="primary">Add Drink</button>&nbsp;
 <span class="span-fill-remaining-space"></span>
 <login-buttons></login-buttons>
</md-toolbar>
<router-outlet></router-outlet>

现在我尝试浏览应用程序，我收到很多错误：

我的 package.json 包含以下内容：

{
  "name": "myalcoholist-meteor",
  "private": true,
  "scripts": {
    "start": "meteor run"
  },
  "dependencies": {
    "@angular/common": "^2.0.0-rc.1",
    "@angular/compiler": "^2.0.0-rc.1",
    "@angular/core": "^2.0.0-rc.1",
    "@angular/platform-browser": "^2.0.0-rc.1",
    "@angular/router": "^2.0.0-rc.1",
    "@angular2-material/button": "^2.0.0-alpha.4",
    "@angular2-material/core": "^2.0.0-alpha.4",
    "@angular2-material/toolbar": "^2.0.0-alpha.4",
    "angular2-meteor": "^0.5.5",
    "angular2-meteor-auto-bootstrap": "^0.5.5",
    "es6-shim": "^0.35.0",
    "meteor-node-stubs": "^0.2.3",
    "reflect-metadata": "=0.1.2",
    "rxjs": "=5.0.0-beta.6",
    "zone.js": "^0.6.12"
  }
}

现在..当我[routerLink]从 html 中删除该属性时，错误就消失了。我没有正确使用它吗？

更新

这（当前）在新路由器中无效：

<button md-raised-button color="primary" [routerLink]="['/Welcome']">

改为使用

<a md-raised-button color="primary" [routerLink]="['/Welcome']">

还要确保/Welcome路由注册的路径。新路由器使用路径 onyl 导航到，不再有路径名称（我的一些怀疑，因为大写W）

原来的

进口变了。

改为使用

import {APP_BASE_HREF } from '@angular/common';

另请参阅Location 和 HashLocationStrategy 在 beta.16 中停止工作

设置基本 href 的另一种方法是使用

<base href="/">

尝试将此标签放在主要组件的头标签内，并尝试这是否解决了您的问题
