[shoucandanghehe]

在Windows平台上使用nb-cli运行bot，并且设置FASTAPI_RELOAD=false时，Ctrl-C退出bot报错：

使用python bot.py运行正常

环境：

• Windows 11 22623.1245
• PowerShell 7.3.1
• Python 3.11.1 bot-venv
• nonebot2 2.0.0rc3
• Python 3.9.12 nb-cli-venv
• nb: nonebot cli version 1.0.3 使用pipx安装

上游问题，随机触发，忽略即可

nbcli也是运行的python bot.py没区别

上游问题

猜到了（ 或许可以创建一个label upstream issues

随机触发，忽略即可

不过触发概率我这边测是10/10（

你可以试试启动nb然后啥也别连，等两三秒，再ctrl c

这问题uvicorn和starlette都得背一点锅，uvicorn在Windows上的处理到现在没修，starlette把CancelledError给捕获了
