title: My npm start for react tutorial project is not working
body: <p>I am trying to learn react and following egghead's video tut from <a href="https://egghead.io/lessons/react-react-fundamentals-development-environment-setup?series=react-fundamentals" rel="nofollow">https://egghead.io/lessons/react-react-fundamentals-development-environment-setup?series=react-fundamentals</a> on setting up my dev environment. However, after installing relevant modules as mentioned in the first video, when I try npm start, it is throwing following error:</p>
