Vue2.x使用echarts 在echarts实例化时报错

问题遇到的现象和发生背景
问题相关代码,请勿粘贴截图

index.html中引入echarts文件

<!-- 引入echarts文件后 window.echarts -->
        <script src="static/lib/echarts.min.js"></script>

在main.js中 将全局echarts挂载到Vue的原型对象上

// 将全局echarts挂载到Vue的原型对象上
// 别的组件中 this.$echarts
Vue.prototype.$echarts = window.echarts

在trendCom.vue中实例化echarts对象

this.chartInstance = this.$echarts.init(this.$refs.trend_ref)

运行结果及报错内容
[Vue warn]: Error in mounted hook: "TypeError: Cannot read properties of undefined (reading 'getAttribute')"
