Highcharts错误：[TypeError：无法读取undefined的属性'prototype']

标签： javascript node.js highcharts jsreport

我一直在尝试在我的javascript代码中使用Highcharts模块来派生包含图表的PDF文档。我已按照此页面中给出的示例进行操作：Highcharts link这是我的代码：

var fs = require('fs');
var Highcharts = require('highcharts');

require('highcharts/modules/exporting')(Highcharts);
var chart = Highcharts.chart('container', {
  series: [{
    data: [1, 3, 2, 4]
  }],
});

var jsreport = require('jsreport-core')()

jsreport.init().then(function () {     
   return jsreport.render({ 
    template:{
      content : '<div>{{:ch}}</div>',
      engine : 'jsrender',
      recipe : 'phantom-pdf'
    },
    data : {
      ch:chart
    }
    }).then(function(resp) { 
     fs.writeFile(__dirname+'/random.pdf',resp.content)
     // console.log(resp.content.toString())
   });
}).catch(function(e) {
  console.log(e)
})

我收到以下错误：

有人可以建议我解决这个问题的方法吗？ 提前谢谢。
