芹菜在get_scheduler上击败TypeError

Question

试图设置运行 Python3.5， Django==1.10.2和 celery==4.0.2的芹菜，但正在使用主管，但在site-packages/celery/beat

上遇到此错误

我以前在其他项目中成功使用过芹菜，但与Django没有。我遵循此处指定的设置。我可以错过什么吗？

所有邪恶的根都在主管配置文件中，即/etc/supervisor/conf.d/celer_beat.conf.conf ：

command=/home/user_one/venv/app_one/bin/celery -A app_one beat --loglevel=INFO -S django

-S django是指我不使用的django_celery_beat。因此，然后将其更改为：

command=/home/user_one/venv/app_one/bin/celery -A app_one beat -s /home/user_one/apps/app_one/celerybeat-schedule --loglevel=INFO

这样，芹菜在应用程序目录中使用文件(即/home/user_one/apps/app_one/目录。
