angular2-google-maps with angular2 app

我已经设置了angular2-google-mapangular2应用程序.

这是app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent }  from './app.component';
import { AgmCoreModule} from 'angular2-google-maps/core';
@NgModule({
  imports:      [ BrowserModule, AgmCoreModule.forRoot({apiKey: 'AIzaSyAe3ci9yavJcWt7MaJE8DusAuZo-QeRqkU'}) ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ],
})
export class AppModule { }

我用命令安装了angular2-google-maps,

npm install angular2-google-maps --save

哪个成功安装.当我用npm start运行应用程序时,它显示错误说,

http:// localhost:3000/angular2-google-maps/core无法加载资源:服务器响应状态为404(未找到)

但我可以在node_modules中看到angular2-google-maps文件夹.问题是什么？

你忘了加入map了system.config.js

'angular2-google-maps/core': 'npm:angular2-google-maps/core/core.umd.js'

通过将以上内容添加到systemjs配置中.core.umd.js尝试导入时,模块加载器将理解加载angular2-google-maps/core.
