猜測可能是因爲沒有權限讀寫，ls -la看下文件權限設置情況
[root@root vendors]# ls -la
drwxr-xr-x 307 root root 12288 Jun 5 23:08 node_modules
-rwxr-xr-x 1 root root 5880 Jun 5 23:06 package.json
-rw-r--r-- 1 root root 900847 Jun 5 23:06 package-lock.json
只有root用戶組有讀寫權限，其他只讀，將node_modules文件夾修改權限，再執行看看
[root@root vendors]# npm i --production

經過面向搜索引擎開發，有提到用sudo，但是發現還是不行，實際原因是由於用的是root賬戶權限執行npm，而npm默認是不適用root權限創建內容，因此會出現權限問題而導致失敗，加上參數--unsafe-perm=true --allow-root即可解決問題。
npm install --production --unsafe-perm=true --allow-root
