推荐答案
使用SystemJS，您可以提供映射以从其他位置加载模块.
With SystemJS you can provide a mapping to load module from a different location.
SystemJS.config({
map: {
'@angular': 'https://npmcdn.com/@angular'
}
});
这会将模块@angular的所有加载重定向到该CDN位置.
This will redirect all loading of a module @angular to that cdn location.
有关详细信息，请在此 plunker 中查看systemjs.config.js
