osx - Having problems with php artisan serve using laravel -

I am getting this error when I try to execute the php artisan service command on laural 5.0 on my terminal.

  Failed to listen to localhost: 8000 (cause: php_network_getaddresses: getaddrinfo failed: node name or pronoun, or not known)  

I'm on Mac using the map, my / etc / hosts file contains:

  127.0.0.1 localhost 255.255.255.255 Broadcast Host :: 1 Local Host fe80 :: 1% Low Local Host < / Code>
