Python芹菜worker_main“RuntimeError：超过最大递归深度”

我正在研究基于Celery的应用程序，并希望从主函数中启动工作程序。下面是代码的一个非常简化的版本：Python芹菜worker_main“RuntimeError：超过最大递归深度”

from celery import Celery 

class CoolApp(object): 
    def __init__(self): 
     self.app = Celery('test', 'amqp://[email protected]/') 

test = CoolApp() 

test.app.worker_main()

这将产生一个错误RuntimeError: maximum recursion depth exceeded in cmp，我想不通为什么。请帮忙。

在红帽企业Linux工作站版本7.3（Maipo）上使用celery 4.0.2 – Jordan

我也面临同样的问题。有人可以帮忙吗？在此先感谢:)。 –

我得到了同样的错误，当我试图把芹菜3.1.25升级到4.1.0。因此基本上在4.1.0中几乎没有被使用的软件包。所以请确保您没有使用最新版本中废弃的类。在我来说，我使用celery.worker.job.Request这是在3.1.25过时，现在是celery.worker.request.Request

我希望这会帮助你。
