使用 Print 进行简单的芹菜测试不会进入终端

EDIT 1:

实际上，print语句输出到 Celery 终端，而不是运行 python 程序的终端 - 正如@PatrickAllen 所示

OP

我最近开始使用Celery http://www.celeryproject.org/，但甚至无法进行简单的测试，在等待 30 秒后将一行打印到终端。

In my tasks.py:

from celery import Celery

celery = Celery(__name__, broker='amqp://guest@localhost//', backend='amqp://guest@localhost//')

@celery.task
def test_message():
    print ("schedule task says hello")

在我的包的主模块中，我有：

import tasks.py


if __name__ == '__main__':
    <do something>
    tasks.test_message.apply_async(countdown=30)

我从终端运行它：

celery -A tasks worker --loglevel=info

任务运行正确，但主程序的终端上没有任何内容。芹菜产量：
