Angular2未能更新到RC7 - zone.js和反射元數據

我試圖讓我的應用程序運行與新的RC7的角度，但我似乎無法完成，作爲控制檯喊：Angular2未能更新到RC7 - zone.js和反射元數據

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

當這個莫名其妙消失，這會彈出：

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

貌似實現改變，而我不更新，雖然我npm install來回編一切米從無到有，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：（我也試過指的unpkg.com的包，沒有成功）

<html>

    </head> 

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

    </body> 

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

任何想法如何解決這一問題？

在此先感謝！ :)

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

@micronyks你是什麼意思？ –

您正在安裝Angular2.0（最近發佈的軟件包）如果您正在尋找RC7軟件包，請參閱http://stackoverflow.com/questions/39496055/which-angular-forms-version-for-angular-2- rc7/39496132＃39496132在那裏我已經顯示RC5包與systemjs不是webpack。 – micronyks

票據：

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

從的index.html刪除angular2-polyfills.js

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

逸岸，如果你有angular2文件夾下node_modules然後刪除該文件夾。最新的angular2軟件包將可用於@angular文件夾下的node_modules。

你基本上說我應該刪除依賴關係angular2從我的'包。json'只是重新'npm我'？（更新我的'package.json'依賴關係到-rc.7） –

而angular2包似乎並不存在於node_modules下的@angular裏： –

清理node_modules文件夾，然後運行'npm install'它會在node_modules下爲您提供@angular內的包。 – Sanket
