想要实现的效果

示例地址

实现过程

踩坑

1. 示例是通过script引入的依赖，但本人需要在react项目中实现该效果。
2. 按照react-globe.gl官方方法引入总是报错 Can't import the named export 'AmbientLight' from non EcmaScript module (only default export is available)。
3. 原因是通过import Globe from 'react-globe.gl';引入的是.mjs文件，react-globe.gl.mjs。
4. 尝试各种方法都失败，最终通过改为引入.js文件import Globe from "../../node_modules/react-globe.gl/dist/react-globe.gl.min";成功。

安装依赖
