我花了一整天的时间来研究这个问题，但还是没有弄明白。虽然我遵循了正确的命令，正如celery 医生所说：celery -A tasks worker -l info但我仍然收到一个错误，说
You are using `-A` as an option of the worker sub-command:
celery worker -A celeryapp <...>
The support for this usage was removed in Celery 5.0. Instead you should use `-A` as a global option:
celery -A celeryapp worker <...>在我的Celery的Dockerfile中，我执行Celery的命令是：
ENTRYPOINT ["celery", "-A", "tasks", "worker", "-l", "info"]在Heroku资源中，它仍然显示预期的命令：
但是当Heroku正在建造时，我收到了这个错误

我在一个几年没碰过的老堆栈上工作时被这个问题难倒了。
在我的例子中，我使用supervisor运行celery，在更新
/etc/supervisor/conf.d/appname-celery.conf文件中的celery命令后，我需要运行两个supervisor命令。本文档中介绍了这些命令，如下所示：
我可以通过使命令行无效，向celery的预期位置添加一些随机字符来测试我的supervisor配置更新没有被选中。
另一种我知道出错的方法是在正确的虚拟环境中从命令行运行“正确的”命令。这样做，我可以看到celery 开始如预期。
它采取了一些挖掘到上述做步行通过。tldr;它不是celery，而是supervisor使用的缓存配置，它正在运行celery。
