Celery AttributeError：异步错误 [英] Celery AttributeError: async error

问题描述

我在Mac（OS / X 10.13.4）上本地运行RabbitMQ和Celery，当我运行add.delay（x，y）时，以下代码在本地运行：

I have RabbitMQ and Celery running locally on my Mac (OS/X 10.13.4), the following code works locally when I run add.delay(x,y):

#!/usr/bin/env python
from celery import Celery
from celery.utils.log import get_task_logger

logger = get_task_logger(__name__)

app = Celery('tasks', \
        broker='pyamqp://appuser:xx@c2/appvhost', \
        backend='db+mysql://appuser:xx@c2/pigpen')

@app.task(bind=True)
def dump_context(self, x, y):
    print('Executing task id {0.id}, args: {0.args!r} kwargs {0.kwargs!r}'.format(self.request))

@app.task
def add(x, y):
    logger.info('Adding {0} + {1}'.format(x, y))
    return x + y

但是，当我尝试在运行Kali 2018.2的ODROID-C2上运行Celery worker时（当前更新） ，在运行 celery -A任务工作程序--loglevel = info 时出现以下错误：

However when I try to run the Celery worker on an ODROID-C2 running Kali 2018.2 (w. current updates, I get the following error when running celery -A tasks worker --loglevel=info:

从Kali ODROID，我可以使用Python Pika脚本连接到名为c2的主机上的RabbitMQ实例，并且该设备上的mysql可以在c2机器上运行也一样我发现了类似的错误，但这些解决方案都不适合我。

From the Kali ODROID I am able to connect to the RabbitMQ instance on the host named c2 using a Python Pika script and mysql from that device works to the c2 machine as well. I have found similar errors, none of those solutions have worked for me.

通过pip安装在ODROID-C2上的芹菜版本为：

Celery version installed on the ODROID-C2 via pip is:

celery --version
4.1.0 (latentcall)

推荐答案

我们仅更新为celery == 4.1.1

We sorted by just updating to celery==4.1.1

4.1.X的发行版整理出了kombu上的模块名称更改

it seems the latest release for the 4.1.X sorted out the module name change on kombu
