从app.module.ts文件中的'angular'导入*为角度

Question

我已经使用angular2(升级选项)将angular1应用程序升级为bootstrap,但在使用systemJS config导入angular后:

map: {... 'angular': 'npm:angular/angular.js' ... }

浏览器发送错误:

systemjs.import error: Error: (SystemJS) angular.module is not a function
    TypeError: angular.module is not a function
        at execute (http://msoqa05.devlab.ad:8088/home/bl/app.module.js:88:21)

也许我不理解它,但为了导入角度我需要在systemjs.config中映射它？为什么？

我正在尝试降级app.module.ts中的angular2 componentsnet:

import * as angular from 'angular'; 
import { downgradeComponent } from '@angular/upgrade/static';

angular.module('myApp')
    .directive(
        'helloWorld',
        downgradeComponent({component: HelloWorldComponent}) as angular.IDirectiveFactory
    );

ts编译没问题,但浏览器不能正常使用它我得到了这个错误.angular.module是angularJS的基础？

这样做解决了这个问题:无需使用systemjs导入角度.

import * as _angular_ from 'angular';

declare global {
  const angular: typeof _angular_;
}
