I am getting this error when trying to load angular2 page:

                '@angular': '/js/node_modules/@angular',
                'rxjs': '/js/node_modules/rxjs'
            }
        });
        System.import('app')
                .then(null, console.error.bind(console));
    </script>

    <!-- end AngularJS 2-->
</head>

<body>

<root-component>Loading...</root-component>

</body>
</html>

What is going on ? Why is it not finding SystemJS ...

NOTE: My folder structure is that the app is located under assets/management folder like so:

management/
├── app/
|   ├──root/
│       ├── root.component.ts
|       ├── root.module.ts
├──main.ts

NOTE2: removing System.import ... results in the error not being thrown

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

回答1:

I bet you need to first load system.src.js and then system-polyfills.js. You're doing it the other way around now.

<script src="/js/node_modules/systemjs/dist/system.src.js"></script>
<script src="/js/node_modules/systemjs/dist/system-polyfills.js"></script>

See: https://github.com/systemjs/systemjs#promise-polyfill
