当我使用npm版本4.6.1运行angular 2应用程序时，我遇到了以下错误。我的构建和gulp在项目中运行良好。任何评论/帮助表示赞赏。感谢。

app.component.ts 

import { Component } from '@angular/core';

应用-routing.module.ts 

import { ModuleWithProviders } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
//Before
import { CDSEDetailsComponent, DirectDebitBankDetailsComponent, MachineDetailsComponent, } from "./reports";
//After
import { CDSEDetailsComponent } from "./reports/cdse-details/cdse-details-component";

import {MachineSearchComponent} from "./search/machine-search-component";

const routes: Routes = [
  {
    component: MachineDetailsComponent,
    data: { menuKey: "pOverview", title: Machine Details" },
    path: "machineDetails/:vId/:gid",
  },
  {
    component: MachineSearchComponent,
    data: { menuKey: "machineSearch", title: "Search for a Machine" },
    path: "machineSearch",
  },
  {
    component: DirectDebitBankDetailsComponent,
    data: { menuKey: "DirectDebitBankDetails", title: "DGR Direct Debit Bank Details" },
    path: "directDebitBankDetails",
  },
  {
    component: CDSEDetailsComponent,
    data : { title : "CDSE Details Report"},
    path: "CDSEDetailsReport",
  },
  {
    redirectTo: '/pOverview',
    path: '',
    data: { menuKey: "pOverview", title: "Ps Overview" },
    pathMatch: 'full'
  }
];

export const appRoutingProviders: any[] = [];

export const routing: ModuleWithProviders = RouterModule.forRoot(routes);

最后route.service.ts 

import { Injectable } from '@angular/core';
import { Router, NavigationEnd, NavigationStart } from '@angular/router';

@Injectable()
export class LastRouterService {
  lastRoute = "";

  constructor(router: Router) {
    router.events.pairwise().subscribe((e) => {
      if (e[0] instanceof NavigationEnd && e[1] instanceof NavigationStart) {
        this.lastRoute = (e[0] as NavigationEnd).urlAfterRedirects;
      }
    });
  }
}

app.component.html 

<ng2common-site-header></ng2common-site-header>
<div class="full height">
  <app-mainmenu></app-mainmenu>
  <div class="content">
    <router-outlet></router-outlet>
  </div>
  <ng2common-site-footer [jurisdiction]="ABC"></ng2common-site-footer>
</div>

main.ts 

import './polyfills.ts';

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { enableProdMode } from '@angular/core';
import { environment } from './environments/environment';
import { AppModule } from './app/';

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

platformBrowserDynamic().bootstrapModule(AppModule);

index.ts在src / app文件夹下 

export * from "./app.component";
export * from "./app.module";

的index.html

上述错误的解决方案正在纠正我在组件下面导入的方式

在

import { CDSEDetailsComponent, DirectDebitBankDetailsComponent, MachineDetailsComponent,} from "./reports";

在

import { CDSEDetailsComponent } from "./reports/cdse-details/cdse-details-component"; import { DirectDebitBankDetailsComponent } from "./reports/direct-debit-bank-details/direct-debit-bank-detai‌​ls-component"; import { MachineDetailsComponent } from "./reports/machine-details/machine-details-component";

以上更改需要在app.module＆amp; APP-routing.module
