title: error in running an react js application in windows
body: <p>I'm using <code>node(12.16.2)</code> and <code>npm(6.14.4)</code> and <code>create-react-app(3.4.1)</code>.
  After creating an app with <code>create-react-app {app name}</code> and going to its directory, I run it with <code>npm start</code> I see error below.
  I think the problem is with my npm not spawn.
  Here is the error:</p>
