m install 報錯，提示gyp ERR! stack Error: EACCES: permission denied
猜測可能是因為沒有權限讀寫，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 > jsonpath@1.0.2 postinstall /www/server/yapi/vendors/node_modules/jsonpath > node lib/aesprim.js > generated/aesprim-browser.js sh: generated/aesprim-browser.js: Permission denied npm WARN mongoose-auto-increment@5.0.1 requires a peer of mongoose@^4.1.12 but none is installed.

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
