Node.js 第三方包的安装、升级、卸载，以及包依赖管理

本地安装： npm install package-name

全局全装： npm install -g package-name

举个栗子

全局安装 React项目的脚手架 npm install -g create-react-app

npm install iview@1.0.1 --save

cnpm install iview@2.13.0 --save //注：重新安装会覆盖旧的版本，比如版本会覆盖上面的1.0.1

升级： npm update

卸载： npm uninstall

例如：

包依赖管理，通过package.json

例如：npm uninstall babel-plugin-import -S//卸载了一个生成包
