未捕获的 ReferenceError:要求未在 angular2 中定义 [英] Uncaught ReferenceError: require is not defined in angular2
问题描述
<html>
<head>
<title>Angular 2 QuickStart</title>
<!-- 1. Load libraries -->
<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="node_modules/rxjs/bundles/Rx.umd.js"></script>
<script src="node_modules/angular2/bundles/angular2-all.umd.js"></script>
<!-- 2. Load our 'modules' -->
<script src='app/app.component.js'></script>
<script src='app/boot.js'></script>
<!--upgrade-->
<script src="node_modules/angular2/upgrade.js"></script>
</head>
<!-- 3. Display the application -->
<body>
<my-app>Loading...</my-app>
</body>
</html>
没有 <script src="node_modules/angular2/upgrade.js"></script> 代码工作正常.当我包含 upgrade.js 时，它显示Uncaught ReferenceError: require is not defined in angular2".我该如何克服这个错误.

推荐答案
require 函数由 SystemJS 提供.您需要将其添加到您的 script 中:
The require function is provided by SystemJS. You need to add it into your script:
<script src="node_modules/systemjs/dist/system.src.js"></script>
<script src="node_modules/angular2/bundles/angular2-polyfills.js"></script>
<script src="node_modules/rxjs/bundles/Rx.umd.js"></script>
<script src="node_modules/angular2/bundles/angular2-all.umd.js"></script>
