Angular2未能更新到RC7 - zone.js和反射元数据

我试图让我的应用程序运行与新的RC7的角度，但我似乎无法完成，作为控制台喊：Angular2未能更新到RC7 - zone.js和反射元数据

Promise rejection: Zone.assertZonePatched is not a function  angular2-polyfills.js:489

当这个莫名其妙消失，这会弹出：

Reflect.getMetadata is not a function (..)        core.umd.js:472

貌似实现改变，而我不更新，虽然我npm install来回编一切米从无到有，更新我的package.json如下：

{ 
    "name": "angular2-quickstart", 
    "version": "1.0.0", 
    "scripts": { 
    "build": "webpack",

    }, 
    "devDependencies": { 
    "ts-loader": "^0.8.2" 
    } 
}

index.html的：（我也试过指的unpkg.com的包，没有成功）

<html> 

    <head>

    </head> 

    <!-- 3. Display the application -->

    </body> 

    <script src="node_modules/angular2/bundles/angular2-polyfills.js"></script> 
    <script src="dist/bundle.js"></script> 
</html>

任何想法如何解决这一问题？

在此先感谢！ :)

您的'package.json'属于'Angular2.0'版本。 – micronyks

@micronyks你是什么意思？ –

您正在安装Angular2.0（最近发布的软件包）如果您正在寻找RC7软件包，请参阅http://stackoverflow.com/questions/39496055/which-angular-forms-version-for-angular-2- rc7/39496132＃39496132在那里我已经显示RC5包与systemjs不是webpack。 – micronyks

票据：

按的package.json，你正在使用Angular2.0.0你不需要angular2-polyfills.js
删除“angular2”：“2.0.0-beta.17”，from 的package.json

从的index.html删除angular2-polyfills.js

<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>

逸岸，如果你有angular2文件夹下node_modules然后删除该文件夹。最新的angular2软件包将可用于@angular文件夹下的node_modules。

你基本上说我应该删除依赖关系angular2从我的'包。json'只是重新'npm我'？（更新我的'package.json'依赖关系到-rc.7） –

而angular2包似乎并不存在于node_modules下的@angular里： –

清理node_modules文件夹，然后运行'npm install'它会在node_modules下为您提供@angular内的包。 – Sanket
