Jenkins 部署 vue 项目 npm install 报错

Question

用 Jenkins 部署项目时,经常报错,差不多 5,6 次报错一次

记录了2次的报错信息如下:

第一次报错:

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

---

第二次报错:

因为没有定位到原因,只能手动删除 node_moudles

在各论坛找到说 "权限不够" 推荐使用: 获取最高权限

npm install --unsafe-perm=true --allow-root

可是只是偶尔出现这个问题,不是必现的,当删除掉 node_moudles 后再次部署不会报错 , 那时也没有用到最高权限

求大佬解惑 ~

说明你这个机器环境，同时多个用户在使用，如果某次是root用户触发的 npm install -g 则会导致 npm 全局目录下某文件夹权限修改为root，这个时候另一个非root用户也在操作同一个 path 自然会出现权限问题。
