Angular2 系统问题

Question

我有这个简单的 TypeScript Angular 2 个例子：

test.ts

import {Component} from 'angular2/core';

@Component({
    selector: 'my-app',
    template: '<div>Test</div>'
})

export class TestComponent {}

main.ts

import {bootstrap} from 'angular2/platform/browser'
import {TestComponent} from './components/test.component/test'

bootstrap(TestComponent);

index.html

<html>
    <head>
        <title>This is an Angular 2 test</title>

        <!-- Angular dependencies -->
        <script src="/node_modules/es6-shim/es6-shim.js"></script>
        <script src="/node_modules/systemjs/dist/system-polyfills.js"></script>
        <script src="/node_modules/angular2/bundles/angular2-polyfills.js"></script>
        <script src="/node_modules/systemjs/dist/system.src.js"></script>
        <script src="/node_modules/rxjs/bundles/Rx.js"></script>
        <script src="/node_modules/angular2/bundles/angular2.dev.js"></script>

        <!-- App -->
        <script>

            System.config({
                packages: {
                    '/': {
                        format: 'register',
                        defaultExtension: 'js'
                    }
                }
            });

            System.import('main').then(null, console.error.bind(console));

        </script>

    </head>
    <body>
        <my-app></my-app>
    </body>
</html>

最后，当我运行 'tsc' 和我的部署脚本时，node_modules/angular2、node_modules/systemjs、node_modules/rxjs 和 node_modules/es6-shim 文件夹被复制连同编译的 JavaScipt 文件。然后，当我尝试打开 index.html 时，我得到的是：

Uncaught ReferenceError: require is not defined(anonymous function) @ browser.ts:1

angular2-polyfills.js:138 Error: http://localhost:8080/node_modules/angular2/platform/browser.js did not call System.register or AMD define.

core.ts:6 Uncaught ReferenceError: require is not defined

有人可以帮我解决这个问题吗？我似乎在做与 Angular2 5 分钟快速入门 (https://angular.io/guide/quickstart) 差不多的事情，它只是拒绝为我工作。

感觉我还需要将依赖库添加到 systemjs，但我不确定这样做的正确方法是什么以及 angular2 人员如何让他们的 quistart 演示与简单的 <script></script> 标签。

tsconfig.json

{
    "compilerOptions": {
        "target": "ES5",
        "module": "system",
        "moduleResolution" : "node",
        "sourceMap": true,
        "emitDecoratorMetadata": false,
        "experimentalDecorators": false,
        "removeComments": true,
        "noImplicitAny": true,
        "noEmitOnError": true,
        "outDir": "build"
    },

    "exclude": [
        "build",
        "bundle",
        "node_modules",
        "public",
        "scss",
        "html",
        "templates",
        ".sass-cache"
    ]
}

我认为问题出在您的 SystemJS 配置级别：

System.config({
  packages: {
    '/': { <----------------
      format: 'register',
      defaultExtension: 'js'
    }
  }
});

您应该使用包含您的 TypeScript 源文件的子文件夹更新它。类似的东西：

  System.config({
    packages: {        
      app: {
        format: 'register',
        defaultExtension: 'js'
      }
    }
  });
