Windows下Celery v4.3.0使用gevent时参数报错及并发数配置问题

Got it, let's sort this out for you!

The issue with your original command is that you're trying to pass gevent as a standalone argument at the end, which Celery 4.x doesn't recognize anymore. Instead, you need to explicitly specify the pool type using the -P (or --pool) flag, and then pair it with the -c (or --concurrency) flag to set the number of concurrent greenlets.

Here's the correct command that combines both your requirements:

celery worker -A celery_blog -l info -P gevent -c 5

补充说明： #

• -P gevent 告诉Celery使用gevent池来处理并发任务（考虑到你在Windows系统上，这是处理异步任务的合适选择）。
• -c 5 将并发级别设置为5，意味着Celery会生成5个协程来同时处理任务。

如果你偏好更清晰的长格式参数（后续查看时更容易理解），也可以使用这种写法：

celery worker -A celery_blog --loglevel=info --pool=gevent --concurrency=5

这个命令完全适配你的环境（Windows 10 + Celery v4.3.0 + gevent），能解决你之前遇到的「unrecognized arguments」错误。
