  <p>I have gone through <a href="https://github.com/facebook/create-react-app/issues/4745" rel="nofollow noreferrer">this</a> and <a href="https://stackoverflow.com/q/55399213/11625619">this</a></p>
  
  <p>I uninstalled the old <code>node</code>, deleted all the files, and installed new <code>node</code>, and then tried to create <code>react project</code> but still I'm facing the same <code>issue</code>.</p>
  
  <p><strong>Note:</strong>  Few days ago, I made some changes to my <code>environment variables</code>, I don't know will that effect some <code>settings</code> ? </p>
  
  <p>Please leave your precious comments.</p>
  
  <p>Thank you.</p>
