echarts用于node中导出PDF

Question

问题描述

const jsdom = require("jsdom");
const echarts = require('echarts')
var d3 = require('d3');
const { JSDOM } = jsdom;
const html2canvas = require('html2canvas')
const {createCanvas} = require('canvas')
require('zrender/lib/svg/svg');

const myPDFcanvas = createCanvas(600, 800)
echarts.setCanvasCreator(() =>  myPDFcanvas)
console.log(containerDom,'containerDom')
const chart = echarts.init(containerDom, null, {
    renderer:'canvas',
})

问题出现的环境背景及自己尝试过哪些方法

这样写终端一直报错 “
dyld: lazy symbol binding failed: Symbol not found: __ZN2v87Isolate19CheckMemoryPressureEv”
