引入地图的时候
echarts2报错：
Uncaught Error: [MODULE_MISS]"echarts/src/util/mapData/params" is not exists!
原因不明，但是感觉和缺js文件有关（因为echarts3报错就是因为缺少了world.js）
echarts3报错：
Uncaught TypeError: Cannot read property \'features\' of undefined
原因如下：缺少world.js，然后成功：
完成以上功能的代码如下：

Echarts报错 Cannot read property ‘init’ of undefined
在vue中使用echarts报错"TypeError: Cannot read property 'getAttribute' of null
Echarts 明明和官方文档配置一致，图表加载却是报错：Error in mounted hook: "TypeError: Cannot read property 'get&#
