EventEmitter error after updating to NPM 3.10 - node.js

Question

I have updated NPM and now my code is returning the following error (please see picture):
Error Message can someone please provide guidance in identifying the culprit? My suspicion is that it has to do with inheritss which I'm not familiar with.
/**
* Expose the constructor.
*/
exports = module.exports = Store;
/**
* Module dependencies.
*/
var EventEmitter = process.EventEmitter;
/**
* Store interface
*
* #api public
*/
function Store (options) {
this.options = options;
this.clients = {};
};
/**
* Inherit from EventEmitter.
*/
Store.prototype.__proto__ = EventEmitter.prototype;
/**
* Initializes a client store
*
* #param {String} id
* #api public
*/
Store.prototype.client = function (id) {
if (!this.clients[id]) {
this.clients[id] = new (this.constructor.Client)(this, id);
}
return this.clients[id];
};
/**
* Destroys a client
*
* #api {String} sid
* #param {Number} number of seconds to expire client data
* #api private
*/
Store.prototype.destroyClient = function (id, expiration) {
if (this.clients[id]) {
this.clients[id].destroy(expiration);
delete this.clients[id];
}
return this;
};
/**
* Destroys the store
*
* #param {Number} number of seconds to expire client data
* #api private
*/
Store.prototype.destroy = function (clientExpiration) {
var keys = Object.keys(this.clients)
, count = keys.length;
for (var i = 0, l = count; i < l; i++) {
this.destroyClient(keys[i], clientExpiration);
}
this.clients = {};
return this;
};
/**
* Client.
*
* #api public
*/
Store.Client = function (store, id) {
this.store = store;
this.id = id;
};

The current way to get the EventEmitter class is:
const EventEmitter = require('events');
You should not be using process.EventEmitter.
In addition, the modern way to subclass an object is using either the ES6 class syntax or using Object.create(), not using __proto__.
