Angular4 Highcharts TypeError 使用要求

Angular4 Highcharts TypeError using require

我正在使用 Angular4 和 angular2-highcharts。根据文档,我需要包含具有 require 属性的 highcharts 模块。它适用于包含 highcharts 模块,但不适用于附加模块(highcharts-more、highmaps 等)。当我包含更多 highcharts 模块时,我会收到如下错误:

TypeError: n is not a function
TypeError: n is not a function
    at highcharts-more.js:8
    at highcharts-more.js:11

我需要实现一个热图,它现在不起作用,因为它使用了额外的模块。知道如何解决这个问题吗?

这是我的 app.module.ts

代码
   // solution for angular not picking up required attribute
    declare const require: any;
    export function highchartsFactory() {
      let hc = require('highcharts');
      let hex = require('highcharts/modules/exporting');
      let hmod = require('highcharts/highcharts-more');
      hex(hc);
      hmod(hex);
      return hc;
    }

    imports: [
        ChartModule,
      ],
    providers: [
    {
      provide: HighchartsStatic,
      useFactory: highchartsFactory
    }
   ]

heatmap 系列类型不在 highcharts-more 文件中。所需的文件是 heatmap - 如本演示所示:

如文档中所述:

我通过在 app.module.ts

中执行以下操作解决了这个问题
declare const require: any;
export function highchartsFactory() {
  let Highcharts = require('highcharts');
  let Heatmap = require('highcharts/modules/heatmap');
  Heatmap(Highcharts);
  return Highcharts;
}
