typeerror: this.set not function @ eventemitter.enabled (/home/ubuntu/workspace/node_modules/express/lib/application.js:421:23) @ eventemitter.lazyrouter (/home/ubuntu/workspace/node_modules/express/lib/application.js:139:27) @ eventemitter.methods.foreach.app.(anonymous function) [as get] (/home/ubuntu/workspace/node_modules/express/lib/application.js:478:10) @ object.

fix these lines :

app.engine('handlebars', hbs({defaultlayout: 'layout'})); app.set('view engine', 'handlebars'); 

and another, change layout.hbs layout.handlerbars
