所以我对celery完全陌生，我一直在尝试遵循文档中的教程，但遇到了问题。当我无法查看芹菜工作者的结果时，就会出现问题。这是我在名为tasks.py的文件中的代码（我具有rabbitMQ设置）：
from celery import Celery
app = Celery('tasks', backend='rpc://', broker='amqp://localhost')
@app.task
def adding(x, y):
return x + y
我使用以下命令运行一个工作器：
celery -A tasks worker --loglevel=info
运行该命令后，这是输出代码：

一旦在这里我不能输入任何内容，并且ctrl-c仅打印我应该再次按ctrl-c退出的内容，但是当我什么也不做时。这不是我的主要问题。我的主要问题是当我使用python控制台按如下方式使用worker时：
from tasks import adding
result = adding.delay(3, 4)
该代码返回AsyncResult，但发生了两件事：
result.get()
python控制台冻结，我无法再输入任何内容。为了重新获得对python控制台的控制，我必须使用ctrl-c，这会引发socket.timeout错误。
有人有解决我问题的想法吗？到处都有教程显示，在运行任务时，首次启动工作程序的原始终端窗口应该更新，并且result.get（）应该返回任务返回的数据。

因为我可以在您的工作台上看到这一行-
Option Explicit

我想您应该尝试使用task events: OFF (enable -E to monitor tasks in this worker)
选项来运行celery-worker，如下所示：
-E我不太确定，但是您可以尝试一下。
