Python Celery 異步任務未執行

Question

我正在學習使用 Celery 在 python 中創建異步任務

這是我的代碼

from celery import Celery
import time

app = Celery("hello", backend="rpc://", broker="amqp://guest@localhost//")


@app.task
def hello():
    time.sleep(5)
    with open("./test.txt", "w+", encoding="utf-8") as fp:
        fp.write("ok")

    return "hello world"

Celery啟動信息

> celery -A main worker -l INFO

[tasks]
  . main.hello

[2021-12-07 08:56:14,018: INFO/MainProcess] Task main.hello[010042fd-4839-
received

打個招呼 function

>>> from main import *

>>> hello.delay()
<AsyncResult: 010042fd-4839-46c0-8602-cf192f6b50b9>

我不知道出了什么問題，文件還沒有創建

版本信息

> python -V
Python 3.10.0

celery==5.2.1

不管在windows上怎么測試都不會成功，於是我在wsl ubuntu上安裝了Python 3.8.10 測試發現可以正確執行異步任務我不知道為什么它在 windows 上不起作用。
