Angular 2 rc1 TypeError: Cannot read property 'annotations' of undefined

Question

我收到 TypeError: Cannot read 属性 'annotations' of undefined error 当我将我的应用程序更新到 rc1 时。知道什么会导致这个问题吗？我应该使用而不是 '@angular/router-deprecated' ,'@angular/router' 吗？[=13=]

 import {Component, provide, Optional, Inject, NgZone} from '@angular/core';
    import {RouteConfig, ROUTER_DIRECTIVES, ROUTER_PROVIDERS} from '@angular/router-deprecated';
    import {CliRouteConfig} from './route-config';
    //import * as Redux from 'redux';

    import {RegisterSimple} from './register-simple/register-simple';
    import {Register} from './register/register';

    @Component({
      selector: 'account-app',
      providers: [],
      template: `
        <h2>Account</h2>
        <nav>
          <a [routerLink]="['RegisterSimple']" class="nav-register-simple">Register Simple</a>
          <a [routerLink]="['Register']" class="nav-register">Register</a>

        </nav>
        <hr>
        <div style="margin:20px; border:1px solid #ccc;">
          <router-outlet></router-outlet>
        </div>
      `,
      directives: [ROUTER_DIRECTIVES, RegisterSimple],
      pipes: []
    })

    @RouteConfig([

      { path: '/register-simple', name: 'RegisterSimple', component: RegisterSimple },
      { path: '/register', name: 'Register', component: Register },

    ].concat(CliRouteConfig))

    export class AccountApp {

      private userState: any = null;

      constructor(
        private ngZone: NgZone,
        @Optional() @Inject('UserStore') UserStore: any
      ) {
        let userData = {
          general: {
            userNodeID: 123,
            username: 'Max.m',
            firstname: 'Max',
            lastname: 'Mustermann',
            salutation: 'Mr',
            birthdate: '23.12.1988'
          },
          address: {
            street: 'Musterstraße',
            houseNumber: '4',
            postCode: '4020',
            city: 'Linz',
            countryCode: 'AT'
          },
          contact: {
            phone: '0123456789',
            email: 'max@mustermann.at',
            newsletter: true
          },
          payment: {
            accountHolderName: 'Max Mustermann',
            bic: 'AT65232323',
            iban: 'AT9837272727272'
          },
          culture: {
            currency: 'EUR',
            language: 'de',
            oddFormat: 'Decimal'
          }
        }

        this.ngZone.runOutsideAngular(() => {
          this.ngZone.run(() => {

          });
        });
      }
    }

Main.ts

import { bootstrap } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { AccountApp, environment} from './app';

if (environment.production) {
  enableProdMode();
}
bootstrap(AccountApp);

Answer 1

看起来 angular bug/version 不兼容。尝试运行 npm 安装，检查 systemjs 配置，package.json，交换路由器版本。

Answer 2

我有同样的错误信息。这是因为我试图运行大多数包（通用、核心等）与 rc.4 和仍然有 rc.1 的路由器（发布时的最新版本）。将其他包移回 rc.1 解决了这个问题。
