在Windows 10中执行带芹菜的花时出错

Question

我正在windows 10中的Django 3中开发一个应用程序。

我已经安装了芹菜、RabitMQ和花。芹菜效果很好，但当我运行时

celery -A proj flower

产生以下错误

不可能导致此错误。

我搜索了文档，没有发现类似的错误。

Answer 1

我已经通过在tornadoplatform中编辑文件asyncio.py来解决问题，添加：

import sys
if sys.platform == 'win32':
asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

Answer 2

我也有同样的错误。你使用哪种版本的python？我的是3.8，然后我改成3.6，一切都正常。
