npm ls -g 查看全局安装的模块及依赖

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

npm rebuild moduleName 用于更改包内容后进行重建

npm outdated 检查包是否已经过时，此命令会列出所有已经过时的包，可以及时进行包的更新

npm update moduleName 更新node模块
