title: npm run build & npm start not working, react app
body: <p>I am a new react student, have no place else to ask this question and can't solve it on my own because I'm really confused, I don't even know how to put this question together properly. I'm following the instructions from a react course.</p>
  <p>I installed node.js, created a new project folder, then in the terminal I wrote <code>create react-app .</code> everything worked, and then wrote <code>npm run build</code> and <code>npm start</code>, but both didn't work.</p>
  <p>Heres the error messages for <code>npm run build</code>:</p>
