在队列那块，使用beanstalkd时：
Beanstalkd: pda/pheanstalk ~3.0 //此处应该用2.1.*
或者
修改Illuminate\Queue\BeanstalkdQueue.php

//use Pheanstalk_Job;
//use Pheanstalk_Pheanstalk as Pheanstalk;
use Pheanstalk\Job;
use Pheanstalk\Pheanstalk;

修改Illuminate\Queue\Connectors\BeanstalkdConnector.php

//use Pheanstalk_Pheanstalk as Pheanstalk;
//use Pheanstalk_PheanstalkInterface as PheanstalkInterface;
use Pheanstalk\Pheanstalk;
use Pheanstalk\PheanstalkInterface;

修改Illuminate\Queue\Jobs\BeanstalkdJob.php

//use Pheanstalk_Pheanstalk as Pheanstalk;
use Pheanstalk\Pheanstalk;
