I started learning nodejs and followed this tutorial to create a simple web app.
https://blog.risingstack.com/node-hero-tutorial-getting-started-with-node-js/
According to the tutorial I can run the web app using either 'npm start' or node index.js' . When I use node install.js it works and give the result. But when I use npm start this error occurs.

As I'm a total beginner to nodejs and npm I can't figure out what went wrong. Does anyone know how to fix this ? Thanks in advance.
