npm 全局安装目录

使用 npm i xxx -g 的都会安装到该目录下；还有使用 npm link 也会有关联的目录在改目录下；

1.使用命令查看 npm 配置信息

npm config ls

# mac会有如下显示：
; "global" config from /usr/local/etc/npmrc

disturl = "https://npm.taobao.org/dist"
; registry = "https://registry.npm.taobao.org/" ; overridden by user

; "user" config from /Users/wuzhiqiang/.npmrc

//localhost:8081/repository/npm-group/:_authToken = (protected)
//localhost:8081/repository/npm-local/:_authToken = (protected)
registry = "https://registry.npmjs.org/"

; node bin location = /usr/local/bin/node
; cwd = /Users/wuzhiqiang/Desktop/文档
; HOME = /Users/wuzhiqiang
; Run `npm config ls -l` to show all defaults.
