Just as a quick suggestion, try changing the host setting of your database configuration to localhost instead of 127.0.0.1

@LukeTowers But before it is localhost will report an error。

The error message doesn't appear to be in English, but error code SQLSTATE[HY000] [2002] means the connection was refused. Here is the solution for fixing the localhost issue: http://anujyadavcse.blogspot.com.au/2014/01/laravel-xampp-mysql-artisan-migrate.html
