title: Getting issues while installing React Project on Windows system
body: <p>I am trying to install a React Web Application on my Windows system. It was working fine earlier but when I re-installed my Windows then it stopped working. I have already installed Node and Npm. </p>
  
  <p>When I run the command <code>npm install</code> it goes well. But when I run the command <code>npm start</code> it throws the following error: </p>
  
  <blockquote>
    <p>REACT_APP_ENV is not recognized as an internal or external command</p>
  </blockquote>
  
  <p>Please see the attached image also:</p>
