记录一个在 laradock 中运行 NPM install 或 yarn install 遇到的坑

将线上的项目 git clone 重新部署到本地的时候（第一次部署到本地OK的，第二次部署到本地另一个位置出问题了），在 laradock 环境中 composer install 安装OK，然后安装vue 环境，执行 npm install 或者 yarn install 的时候，出错：

出现了很多 python , python2 什么的。。。
或者在上面出错的情况下，编译本地文件执行 npm run watch-poll （或 npm run dev）的时候，出现另一种错误：

根据提示 npm install node-sass 或 yarn add node-sass 无效。。。

解决办法：
更换 npm 镜像为阿里镜像：
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install node-sass
