• 安装 nodejs，在项目目录下安装 three.js 模块：npm install --save @types/three

• 在该目录下会有一个 node_modules/@types/three 文件夹

• 在 js 文件中输入 THREE 就会产生提示（参考 https://blog.csdn.net/Mrhan210/article/details/85263755）

• 在 three 中定义的变量都有提示，不过其创建的变量没有提示，可以在变量上添加类似 /** @type {THREE.WebGLRenderer} */ 的说明即可（参考 https://blog.csdn.net/supergao222/article/details/80658525）
