Error: EACCES: permission denied, mkdir ‘/usr/local/lib/node_modules/xxxxxx’
1 问题描述
今天使用 npm i docsify-cli -g 安装 node 脚手架工具时，出现以下错误：
andrew@Andrews-MacBook-Pro CSNotes % npm i docsify-cli -g
npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/docsify-cli
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/docsify-cli'

npm ERR! syscall: 'mkdir',
npm ERR! path: '/usr/local/lib/node_modules/docsify-cli'
npm ERR! }
npm ERR!

看到 Error: EACCES: permission denied 这句话时，该问题很明显是用户权限不足了。
2 解决方案
解决该权限问题核心思想是提权，但有两种思路：
- 对文件目录提权
sudo chown -R $USER /usr/local/lib/node_modules
- 对执行用户提权
sudo npm i docsify-cli -g
最终我们顺利安装成功：
