Node-sass 安装时的坑
clone 的一个项目环境依赖中有 node-sass：
直接 npm install 报错：

在网上找了许多方法都不可行，最后在找到了类似的问题：node.js - error: no template named ‘remove_cv_t’ in namespace ‘std’; did you mean ‘remove_cv’? - Stack Overflow，发现是依赖中 node-sass 的版本不支持 Node.js16 ，只能在 15 及以下的环境下运行，通过 node 版本控制器 n 对使用的 node 进行降级就可以正常安装 node-sass ，安装当前 node 的稳定版本就可以正常使用，使用教程见n - npm (npmjs.com)
