芹菜Windowserror:[错误6]手柄无效

Question

我是新来的芹菜，我正在关注他们网站上给出的教程，我得到了这个错误

 from celery import Celery
 app = Celery('tasks', broker='pyamqp://guest@localhost//')
 @app.task
 def add(x, y):
     return x + y

和cmd显示这样的错误

Answer 1

芹菜在Windows中不再支持4.0以来，如他们的读书中所述：

芹菜是一个具有最低资金的项目，因此我们不支持Microsoft Windows。请不要打开与该平台有关的任何问题。

不幸的是，此错误似乎是副作用之一（支持被删除的过程手柄）

您最好的选择是降级芹菜，然后先删除： pip install celery==3.1.18

Answer 2

看起来您的RabbitMQ服务器未运行。您是否运行安装并启动Rabbimq服务器？

您可以查看RabbitMQ文档并安装它。启动RabbitMQ服务器，然后使用您的应用程序

启动您的芹菜工人

celery worker -l info -A tasks
