echarts引用3d图形首先需要引入echarts其次在引入echarts-gl
import * as echarts from "echarts";
import "echarts-gl";
但是不同版本echarts对应不同版本echarts-gl ,
经常出现echarts echarts-gl对应得版本不一致导致报错,如
“echarts”: “^4.9.0”, “echarts-gl”: “^1.1.2”,
“echarts”: “^5.2.0”, “echarts-gl”: “^2.0.8”,
如果对应版本引入echarts-gl 仍然报错[ECharts] Unkown series surface,
