無法讀取未定義的屬性「拆分」

我在本地服務器上運行以下代碼。無法讀取未定義的屬性「拆分」

<!DOCTYPE html> 
<html> 
<head> 
    <link rel="stylesheet" href="style.css"> 
    <script src="https://jspm.io/[email protected]"></script> 
    <script src="https://code.angularjs.org/2.0.0-alpha.19/angular2.dev.js"></script> 
</head> 
<body> 
    <my-app></my-app> 
    <script> 
    System.config({ 
     paths: { 
      '*': '*.js', 
      'angular2/*': 'angular2/*' 
     } 
}); 
System.import('main'); 
</script> 
</body> 
</html>

以上是index.html頁面。

import {Component, View, bootstrap} from 'angular2/angular2'; 

@Component({ 
    selector: 'my-app' 
}) 
@View({ 
    template: '<h1>My first Angular 2 App</h1>' 
}) 
class AppComponent { 
} 

bootstrap(AppComponent);

以上是main.js文件。

當我在服務器上運行這個時，我在控制檯中得到以下內容。

上述代碼取自官方的角度2網站angular.io。如果在plunkr中執行相同的代碼，我會得到輸出「我的第一個Angular 2應用程序」，但不在我的本地。

我錯過了什麼嗎？

似乎規定，我們必須導入traceur-runtime.js並設置traceur選項。

這裏是plunker link

<!DOCTYPE html> 
<html> 
<head> 
<link rel="stylesheet" href="style.css"> 
<script src="https://github.jspm.io/jmcriffey/[email protected]/traceur-runtime.js"></script> 
<script src="https://jspm.io/[email protected]"></script> 
<script src="https://code.angularjs.org/2.0.0-alpha.19/angular2.dev.js"></script> 
</head> 
<body> 
<my-app></my-app> 
<script> 
System.config({ 
    traceurOptions: { 
     annotations: true, 
     memberVariables: true, 
     types: true 
    }, 
    paths: { 
     '*': '*.js', 
     'angular2/*': 'angular2/*' 
    } 
}); 
System.import('main'); 
</script> 
</body> 
</html>

問題出在您聲明角度應用的文件名。

它應該是的main.es6.js代替main.js

文件名稱格式應始終名字在System.import('main')這是main. + es6. + js

我已經試圖改變文件名。您是否告訴我只需要更改文件名或System.import語句以及它。僅將文件名從main.js更改爲main.es6.js不起作用，則顯示相同的問題。 – Kaushik

@Kaushik我只是說要更改應該解決您的問題的文件名 –
