celery 启动worker 时候报错

Question

错误信息如下：
raceback (most recent call last):
File "/home/xuxiaolong/anaconda3/lib/python3.6/site-packages/celery/app/utils.py", line 228, in find_app
found = sym.app
AttributeError: module 'celeryDemo' has no attribute 'app'

During handling of the above exception, another exception occurred:

当家帮忙看下，我查了好久不知道啥问题

Answer 1

解决方案有2个:

1. 升级python-librabbitmq到新的版本,如 1.5.2 ,可以用通过.deb包或apt-get命令来升级,也可以用pip来安装.我用pip安装默认就到1.5.2版本了,如下:

jay@jay-linux:~$ sudo apt-get remove python-librabbitmq #删除原来的包
jay@jay-linux:~$ sudo pip install librabbitmq

1. 直接删除python-librabbitmq包,这样celery会回到使用python-amqp包,这样也时可以的.
