切换到RC5:多个组件

Question

我在尝试切换到最新的RC5时遇到错误，我不知道这是什么意思：

Error: Template parse errors:
More than one component: DeviceComponent,OtherComponent ("
    </div>
    <div class="col-sm-12 col-md-4 col-lg-4">
        [ERROR ->]<device *ngIf="authService.authenticated"></device>
    </div>

它奇怪地抱怨这个html。

platform.module.ts

import { HttpModule } from '@angular/http';
import { NgModule }       from '@angular/core';
import { BrowserModule  } from '@angular/platform-browser';
import { FormsModule  } from '@angular/forms';
import { PlatformComponent }   from './platform.component';
import {AuthService} from '../../services/auth.service';
import {CookieService} from 'angular2-cookie/core';
import { RouterModule } from '@angular/router';
import {IncrementIndexPipe} from '../../pipes/incrementIndex';
import { TruncatePipe} from '../../pipes/truncate';
import { routing,
         appRoutingProviders } from './platform.component';

@NgModule({
    declarations: [TruncatePipe, IncrementIndexPipe],
    imports:      [BrowserModule,
                   HttpModule,
                   RouterModule,
                   FormsModule,
                   routing],
    bootstrap:    [PlatformComponent],
    providers:    [AuthService, CookieService, appRoutingProviders]
})
export class PlatformModule {}

我还不断地得到：

platform-browser.umd.js:937 ORIGINAL EXCEPTION: No provider for Router!

Answer 1

要解算，请执行以下操作：

platform-browser.umd.js:937 ORIGINAL EXCEPTION: No provider for Router!

我删除了所有旧的@angular2/router-已弃用

要解决“多个组件”错误，就像@rashfmnb建议的那样，(1)删除所有的double @Component修饰符(在我的例子中不是)，(2)删除@Component修饰符中重复的"selector“标记。这是，而不是以前的angular2版本中存在的问题。
