经过今天测试，发现问题出在librabbitmq这个库上面，pip卸载掉这个库就可以运行了，但作者书上写务必使用这个C写的库，求解是否有解决方法？

@escblack 我写书时各个软件的版本正常的，但是不能保证半年后的现在不会做什么不兼容的修改。 我搜了下 https://github.com/celery/celery/search?q=Received+and+deleted+unknown+message&type=Issues&utf8=%E2%9C%93 还挺多的，你可以参考下

看代码是消息的格式有问题，没有task这个头信息。

这里有解决办法-> celery/celery#3689
方法一：
配置文件celeryconfig.py加上这一行
CELERY_TASK_PROTOCOL = 1
方法二：
app = Celery()
app.conf.task_protocol = 1
董大写书时用的是celery v3.1.18，现在celery升级到了4.0，应该是老版本的librabbitmq与最新的celery4.0 Message Protocol协议不兼容造成的（点这里） ，celery4.0默认使用Task messages Version 2 ，而librabbitmq使用Task messages Version 1
