解决

The most common reason for that error is that you have something else already using that port. Try starting it on another port.

  1. webpack-dev-server --host 127.0.0.1 --port 3001        # in package.json file

Make sure your /etc/hosts file includes localhost.Open /etc/hosts

  1. $ sudo vi /etc/hosts

Copy and paste this, if it’s missing:

  1. 127.0.0.1   localhost
  2. 255.255.255.255 broadcasthost
  3. ::1 localhost
  4. fe80::1%lo0 localhost
