Question

<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>代码可以正常工作。当我包括upgrade.js.it时显示“未捕获的ReferenceError：require未在angular2中定义”。如何克服此错误。

Answer 1

require函数由SystemJS提供。您需要将其添加到script：

中

<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>
(...)

Answer 2

模块应该是tsconfig.json中的系统

{
    "version": "1.0.0",
    "compilerOptions": {
        "target": "es5",
        **"module": "system",**
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false,
        "noLib": false,
        "declaration": false
    },
    "exclude": [
        "node_modules",
        "bower_components",
        "jspm_packages",
        "typings/main",
        "typings/main.d.ts"
    ]
}

未捕获的ReferenceError：在angular2
