I am trying to run a sample program in react using expo

I am getting error :

> @ start E:\ReactNative\Samples\rn-starter
> expo start

Starting project at E:\ReactNative\Samples\rn-starter
Expo DevTools is running at http://localhost:19002
Opening DevTools in the browser... (press shift-d to disable)

I had the same issue, it happened when i updated the Node.Js version to 12.13.1, it seems that it's an error in the interpretation of a regular expression:

Option N° 1 :

Inside your project go to

\node_modules\metro-config\src\defaults\blacklist.js

Change :

var sharedBlacklist = [
  /node_modules[/\\]react[/\\]dist[/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

To 

var sharedBlacklist = [
  /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

Option N° 2:

Downgrade your Node.js version to 12.9 or older

Hope this will help you.
