Question

我创建了一个简单的NodeJS / Angular2应用程序，当我尝试访问应用程序的入口点页面时遇到以下错误：

router_1.provideRouter is not a function

我不确定这个错误意味着什么并且不知道从哪里开始。有没有人对于为什么会发生这种情况有任何见解或想法？这是我的package.json文件（因为我认为它可能与其中一个Angular包有关）

{
  "name": "udemy-nodejs-angular2",
  "version": "1.0.0",
  "private": true,
  "scripts": {
    "start": "concurrently tsc -w &&  nodemon ./bin/www",

    "gulp-typescript": "^2.10.0",
    "nodemon": "^1.9.2",
    "typings": "^0.8.1"
  }
}

和我的SystemJS配置：

// map tells the System loader where to look for things
var map = {
    'app': 'js/app', // 'dist',
    'rxjs': 'js/vendor/rxjs',
    '@angular': 'js/vendor/@angular'
};

// packages tells the System loader how to load when no filename and/or no extension
var packages = {
    'app': {main: 'boot.js', defaultExtension: 'js'},
    'rxjs': {defaultExtension: 'js'}
};

var packageNames = [
    '@angular/common',
    '@angular/compiler',
    '@angular/core',
    '@angular/http',
    '@angular/platform-browser',
    '@angular/platform-browser-dynamic',
    '@angular/router',
    '@angular/testing',
    '@angular/upgrade'
];

// add package entries for angular packages in the form '@angular/common': { main: 'index.js', defaultExtension: 'js' }
packageNames.forEach(function (pkgName) {
    packages[pkgName] = {main: 'index.js', defaultExtension: 'js'};
});

var config = {
    map: map,
    packages: packages
};

System.config(config);

以下是我使用路由器功能的地方：

app.routes.ts

import {provideRouter, RouterConfig} from '@angular/router';

import {LoginComponent} from "./components/login/login.component";
import {DashboardComponent} from "./components/dashboard/dashboard.component";


export const routes: RouterConfig = [
    { path: 'login', component: LoginComponent },
    { path: 'dashboard', component: DashboardComponent }
];

export const APP_ROUTER_PROVIDERS = [
    provideRouter(routes)
];

boot.ts：

import {bootstrap} from '@angular/platform-browser-dynamic';

import {AppComponent} from "./app.component";

import { APP_ROUTER_PROVIDERS } from './app.routes';

bootstrap(AppComponent, [
    APP_ROUTER_PROVIDERS
])
.catch(err => console.error(err));

app.component.ts

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

@Component({
    moduleId: module.id,
    selector: 'my-app',
    templateUrl: 'app.template.html',
    directives: [
        ROUTER_DIRECTIVES
    ]
})

export class AppComponent {

}

正如我们在聊天中发现的那样，问题是供应商文件夹中的路由器没有更新到新版本。

要解决此问题，必须删除vendor文件夹下的路由器，然后运行npm install，最后运行npm run gulp重新创建vendor文件夹。

尝试运行Angular2 / NodeJS应用程序时，router_1.provideRouter不是一个函数
