Celery进程的“Worker”以“退出码1”退出

Question

celery worker（Flask应用程序的一部分）在启动之前被终止：

Celery配置参数（Windows，Celery 3.1.25，Rabbitmq（最新版本））

flask_app = Flask(__name__)
flask_app.secret_key = 'some_secret'
flask_app.config['CELERY_BROKER_URL'] = 'amqp://localhost/'
flask_app.config['CELERY_RESULT_BACKEND'] = 'amqp://localhost/'

flask_app.config['CELERY_ACCEPT_CONTENT'] = ['json']
flask_app.config['CELERY_TASK_SERIALIZER'] = 'json'
flask_app.config['CELERY_RESULT_SERIALIZER'] = 'json'
flask_app.config['CELERY_IGNORE_RESULT'] = True

flask_app.config['CELERY_ROUTES'] = {'task': {'queue': 'agent_queue'}}
flask_app.config['CELERY_IMPORTS'] = ['Monitor.app']

结果：

我已经使用celery相当长的时间了，但以前从未遇到过这些问题。

你使用的是哪个版本的Windows？我在Windows 7上已经完美地运行了这个程序，但在Windows Server 2008上运行完全相同的代码会导致这个问题。 - Tom Malkin

Answer 1

我认为这是因为 celery 3.1.25 自带 billiard 3.3 的原因。

如果您将该软件包升级（在撰写本文时升级到 3.5），则服务应该可以正常工作。

pip install --upgrade billiard
