推荐答案
的要求功能由SystemJS提供。您需要将其添加到您的剧本：
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>
