Neo4j Cannot read property 'driver' of undefined

Question

I'v seen every other questions, but it seem that this case is different. Actually, I'm trying to follow this video that is implementring the example https://neo4j.com/developer/javascript/

My code is in 'app.js' is:

var express = require('express');
var path = require('path');
var logger = require('morgan');
var bodyParser = require('body-parser');
var neo4j = require('neo4j-driver').v1;

var app = express();

// View Engine
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', "ejs");

app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false}));
app.use(express.static(path.join(__dirname, 'public')));

var driver = neo4j.driver(
        'bolt://localhost:7687', 
        neo4j.auth.basic('Graph', 'password')
    );
var session = driver.session();

app.get('/', function(req, res){
    session
        .run('MATCH(n:Movie) RETURN n LIMIT 25')
        .then(function(result){
            result.records,forEach(function(record){
                console.log(record);
            })
        })
        .catch(function(){
            console.log(err);
        });
    res.send('It works!!!');
});


app.listen(3000);
console.log('Server Started on Port 3000');

module.exports = app;

With the error is:

var driver = neo4j.driver(
                   ^

The latest version of driver has been moved from .v1 namespace to neo4j namespace. See the readme here - https://www.npmjs.com/package/neo4j-driver

Basically remove .v1 and it should work. like this var neo4j = require('neo4j-driver');
