I am running a JavaScript code on Ubuntu server using node.js
I got this error.

module.js:340

    throw err;

          ^

Error: Cannot find module './lib/compat'

How to debug this error?

Edit: using these dependencies.

var express = require('express');

var fs = require('fs');

var request = require('request');

var cheerio = require('cheerio');
