  * What went wrong:
  A problem occurred evaluating script.
  &gt; Failed to parse React Native CLI configuration. Expected running 'npx.cmd --quiet --no-install react-native config' command from 'D:\xp\feb2020xp\AwesomeProject' directory to output valid JSON, but it didn't. This may be caused by npx resolving to a legacy global react-native binary. Please make sure to uninstall any global 'react-native' binaries: 'npm uninstall -g react-native react-native-cli' and try again

  <p>What I Tried :
  <code>npm uninstall -g react-native react-native-cli</code>
  and 
  <code>npx.cmd --quiet --no-install react-native config</code> </p>
