Installation ERPNext issue : On Centos 7

While execution of “python install.py --production --user frappe”
This is what I got…
Further I am not able to run the application…

TASK [Setup production] ********************************************************
fatal: [localhost]: FAILED! => {“changed”: true, “cmd”: [“bench”, “setup”, “production”, “frappe”], “delta”: “0:00:01.592196”, “end”: “2017-08-01 11:09:38.634599”, “failed”: true, “rc”: 1, “start”: “2017-08-01 11:09:37.042403”, “stderr”: “Aborted!”, “stdout”: "supervisor.conf already exists and this will overwrite it.

Seems supervisor.conf already exists.

Is it the reason why I am not able to access the application…/

What should I do in such case?

do sudo bench setup production

It says … Missing argument User…!

sudo bench setup production frappe

NOTE: frappe should be the user you are using to install bench, site, etc
