npm uninstall xxx (-g) 卸载模块
npm cache clean 清理缓存
npm help xxx 查看帮助
npm view moudleName dependencies 查看包的依赖关系
npm view moduleNames 查看node模块的package.json文件夹
npm view moduleName labelName 查看package.json文件夹下某个标签的内容
npm view moduleName repository.url 查看包的源文件地址
npm view moduleName engines 查看包所依赖的Node的版本
npm help folders 查看npm使用的所有文件夹
