About the Celery service report under win Process 'Worker' exited with 'exitcode 1' [duplicate]

When using the Celery service to run asynchronous tasks or scheduled tasks, although the service starts, an error will be reported:

Celery Process 'Worker' exited with 'exitcode 1' [duplicate]

Causes the task not to run.

After searching, we can locate the problem, because the version of celery's dependency library billiard is too low, which causes the task to be blocked, so the best solution is to upgrade billiard

Execute pip install --upgrade billiard

The official explanation is that billiard is best >= 3.5, so if you are worried, it is better to specify the version number to install
