1. 输入 npm config ls -l 可以查看当前的目录设置

2. 针对某一项设置，可以通过
npm config set 属性名 属性值
的方式来进行配置。
例如:
npm config set prefix "C:3\"
3. 读取某一项配置
npm config get prefix
4.npm的常用命令
npm install xxx 安装模块 npm install xxx@1.1.1 安装1.1.1版本的xxx npm install xxx -g 将模块安装到全局环境中。 npm ls 查看安装的模块及依赖 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npm view moduleName engines 查看包所依赖的Node的版本 npm help folders 查看npm使用的所有文件夹 npm rebuild moduleName 用于更改包内容后进行重建 npm outdated 检查包是否已经过时，此命令会列出所有已经过时的包，可以及时进行包的更新 npm update moduleName 更新node模块
