Question

我对2号角还很陌生，并试图在2号角做活动量表。以“ https://www.highcharts.com/demo/gauge-activity”为例。但是面临连续的错误：-“未捕获的ReferenceError：在solid-gauge.src.js：18上未定义Highcharts”

我的代码：-

App.module.ts

import * as Highcharts from 'highcharts'; 
import * as more from 'highcharts/highcharts-more.src';  
import * as solidGauge from 'highcharts/modules/solid-gauge'; 
import { GauveComponent } from './gauve/gauve.component';
more(Highcharts), 
solidGauge(Highcharts),

component.ts

import { Component, OnInit } from '@angular/core';
import * as Highcharts from 'highcharts'; 
import * as more from 'highcharts/highcharts-more.src';  
import * as solidGauge from 'highcharts/modules/solid-gauge'; 
more(Highcharts);
solidGauge(Highcharts);
import '../../assets/js/gauge.js';
declare var gauvedata: any;

@Component({
  selector: 'app-gauve',
  templateUrl: './gauve.component.html',

constructor() {}
ngOnInit() {
   gauvedata.init();

    return { 
      init: function() {
          alert("inside gauvescript");

Answer 1

发生这种情况是因为highcharts/modules/solid-gauge要求highcharts已被导入。您导入了它，但未导入全局范围，因此其他模块无法引用该变量。

我认为这可以解决您的问题：

import 'highcharts'; 
declare const Highcharts;

Answer 2

像这样尝试：

import { Chart } from 'angular-highcharts';


chart = new Chart({
 // properties
     ...
}
