Pls help NodeJs Installation

Hello Everyone,

Please I am attempting to install an application server using vagrant and linux built on centos. The installation was successful but the application server is not running. I have attempted to trouble-shoot it but no head way yet. Your help will be appreciated.

[vagrant@nodejs ~]$ systemctl status node
a- node.service - NodeJS application server
Loaded: loaded (/etc/systemd/system/node.service; enabled; vendor preset: disabled)
Active: failed (Result: start-limit) since Wed 2020-04-01 02:53:36 EDT; 56s ago
Main PID: 4631 (code=exited, status=1/FAILURE)
[vagrant@nodejs ~]$ ls -Al /etc/modules-load.d/
