Angular2 : ngModule, BrowserModule、FormsModule 不是导出成员

Question

我正在浏览 Angular2 教程 https://angular.io/docs/ts/latest/tutorial/toh-pt5.html .一切都好一步路由。 Visual Studio Code 在第 03 行显示错误:

import { NgModule }       from '@angular/core';
import { BrowserModule }  from '@angular/platform-browser';
import { FormsModule }    from '@angular/forms';

作为

[ts] 
Module '"c:/Users/ktran/Source/Repos/angular2-quickstart-ts/node_modules/@angular/core/index"' has no exported member 'NgModule'.

文件夹 node_modules:

有什么想法吗？

正如 Kim Phung 所说，这是因为刚刚发布了一个新的 Angular RC。更改 packages.json 中的以下行:

// ...snip...
"dependencies": {
    "@angular/common": "2.0.0-rc.5",
    "@angular/compiler": "2.0.0-rc.5",
    "@angular/core": "2.0.0-rc.5",
    "@angular/forms": "0.3.0",
    "@angular/http": "2.0.0-rc.5",
    "@angular/platform-browser": "2.0.0-rc.5",
    "@angular/platform-browser-dynamic": "2.0.0-rc.5",

// ...file continues...

然后在你的控制台中运行:

npm update

干得好!
