Angular2 systemjs issues

问题

I have this simple TypeScript Angular 2 example:

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>

And finally when I run 'tsc' and my deploy scripts the node_modules/angular2, node_modules/systemjs, node_modules/rxjs and node_modules/es6-shim folders are copied together with the compiled JavaSciprt files. Then when I try to open index.html all I get is this:

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

Can someone pls give me a hand with this. I seem to be doing more or less the same thing as the Angular2 5-minute quickstart (https://angular.io/guide/quickstart) and it just refuses to work for me.

It feels like I'd need to also add the dependency libraries to systemjs but I'm not sure what would be the right way to do it and how did the angular2 guys get their quistart demo to work with simple <script></script> tags instead.

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"
    ]
}

I think the problem is at the level of your SystemJS configuration:

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

You should update this using the sub folder containing your TypeScript source files. Something like that:

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

Hope it helps you, Thierry
