解決方法
npm install 添加參數 --unsafe-perm
sudo npm install --global gulp --unsafe-perm
理由
If npm detects it is running as root it drops to a non-privileged user which then doesn‘t have permissions to write to /root/.node-gyp.
##如果NPM檢測到它以根用戶身份運行，它將下降到一個沒有權限寫入/root/.node gyp的非特權用戶。
The --unsafe-perm option stops it from changing user.
nvm doesn‘t have this problem when not using sudo because it stores everything under the current users‘ home directory.
##NVM在不使用sudo時沒有這個問題，因為它將所有內容存儲在當前用戶的主目錄下。
看官方文檔的解釋
unsafe-perm
Default: false if running as root, true otherwise
Type: Boolean
Set to true to suppress the UID/GID switching when running package scripts.##設置為true可在運行包腳本時抑制uid/gid切換。
If set explicitly to false, then installing as a non-root user will fail.
