如何解决Celery 示例在本地机器上引发错误？

开发过程中遇到Celery 示例在本地机器上引发错误的问题如何解决？下面主要结合日常开发的经验，给出你关于Celery 示例在本地机器上引发错误的解决方法建议，希望对你解决Celery 示例在本地机器上引发错误有所启发或帮助；

我正在尝试在本地 windows 计算机上运行最基本的 celery example。为了方便，我复制到这里：

from celery import Celery

app = Celery('tasks',broker='pyamqp://guest@localhost//')

@app.task
def add(x,y):
    return x + y

接下来的说明继续解释 Celery 工作服务器可以在命令行中运行，如下所示：

$ celery -A tasks worker --loglevel=INFO

当我尝试执行此操作时出现错误：

>celery -A tasks worker --loglevel=INFO

我不明白为什么会发生这种情况。字符串是传递给 Celery 类泛型中的可选 broker 参数还是我应该为我的本地机器调整它？我对 RabbitMQ 或代理一无所知，所以我不确定如何解决这个问题。
