Hi, im trying to run the local host but can get it to work.. I get the following error. Is there anyone that can help with this? Also in the app.js file the (req) are faded.

const app = express();

app.set('view engine', 'pug');

app.get('/', (req, res) => { res.render('index'); });

app.get('/cards', (req, res) => { res.render('card', { prompt: "who is buried in the tomb?" }); });

app.get('/hello', (req,res) => { res.render('hello'); });

app.listen(8080, () => { console.log('The application is running on localhost:3000!') });

This is what I get back when I run npm node app.js in terminal

You don't need to use "npm", instead try:

node app.js

Here's a great step by step tutorial about how to run a hello world node app:
