Nodejs Error: Cannot find module .. in ec2

Question

My project tree is look like following:

models/userStore.js

index.js

I am exporting user information in index.js by using following command. const UserStore = require('./models/UserStore');

It is working fine in my local machine. When i upload in ec2 , i am getting following error.

module.js:341
    throw err;
    ^

index.js

 'use strict';

const Hapi = require('hapi');
const HapiSwagger = require('hapi-swagger');
const server = new Hapi.Server();
const Joi = require('joi');
const jwt = require('jsonwebtoken');
const db = require('./db');
const UserStore = require('./models/UserStore');
UserStore.initialize();
const user = UserStore.users; 

server.connection({port: 3000});
server.register(require('./plugins/plugins.js'));

server.register([
    {
        'register': HapiSwagger    
    }
    ], (err) => {
        server.start( (err) => {
           if (err) {
                console.log(err);
            } else {
                console.log('Server running at:' + server.info.uri);
            }
        });
    });


var validate = function (request, decodedToken, callback) {
    var user = UserStore.users[decodedToken.email];
    if (!user) {
      return callback(null, false);
    }
    return callback(null, true, user);
};

server.register(require('hapi-auth-jwt'), function () {
  server.auth.strategy('token', 'jwt', { key: privateKey,
                                         validateFunc: validate,
                                         verifyOptions: { algorithms: [ 'HS256' ] }
                                       });
    server.route(require('./routes/endpoints/routes.js'));
});

Add `console.log(process.env)` in the beginning of `index.js` to test a `NODE_PATH` value. — Roman Dibikhin, Mar 22 '16 at 01:22
Add full stack of the exception, pls. Not only `module.js:341 throw err; ^` — Roman Dibikhin, Mar 22 '16 at 01:23
Perhaps the copy of index.js on EC2 is not updated somehow. The reason I think this is the case is that your provided index.js does not contain `..` anywhere and the line number from the stack trace does not match what is shown in your provided index.js. — mscdex, Mar 22 '16 at 05:18
@LutforRahman you can use lower-case and dashed file names to avoid this in future: `my-module-name.js` — Roman Dibikhin, Mar 22 '16 at 20:37

I fixed the problem. The problem was my file name was(userStore) and when i exported i used (UserStore). As mac is case insensitive, it is running fine locally. As linux file system is case sensitive it throws that error.

more details: Can I force node.js require to be case sensitive?
