Heroku上的芹菜时间/日期错误

Question

我正在使用Celery在Heroku上的Django应用程序上运行一个简单的定期任务。它在本地工作，我可以用观看任务的运行

python manage.py celerybeat

但当我推到heroku并运行时：

heroku run pythonm manage.py celerybeat

我得到：

 [2012-08-24 13:31:43,185: WARNING/MainProcess] __    -    ... __   -        _

出了什么问题？

Answer 1

您应该升级到Celery 3.0.7，它修复了一个与时区相关的错误。

Answer 2

不确定确切的解决方案，但我通过添加绕过了它

USE_L10N = False
USE_TZ = False

设置。py
