官网demo, mapbox->WGS84->地图加载设置 CRS时报错 crs: new mapboxgl.CRS('EPSG:4326',[-180,-90,180,90]), // 或者 mapboxgl.CRS.EPSG4326 或者 new mapboxgl.CRS('EPSG:4326',[-180,-90,180,90]);

使用你发的链接后不报错了，但是如果使用文档中的 head引用JS的话还是会报同样的错误文档 https://iclient.supermap.io/web/introduction/mapboxglDevelop.html#GetLibs

显示非3857投影的地图，需要引入我们扩展的mapbox-gl-enhance.js： https://iclient.supermap.io/web/libs/mapbox-gl-js-enhance/1.12.1/mapbox-gl-enhance.js

这个拓展有NPM的包么 @luoxiao-supermap
