关于在django框架中celery运行beat报OSError: [WinError 87] 参数错误的史诗级大坑

OSError: [WinError 87] 参数错误。

The above exception was the direct cause of the following exception:

运行beat的时候报这个错误，网上都说是版本问题，需要把版本从4.0+降为3.0+，可我的已经是3.1.19了还是有这个错误

我去源码里看了一下，意思好像是杀掉之前的进程失败导致的（os.kill(pid,****)这个代码出错了），我联想到之前beat停止之后再运行会说当前已有beat再运行，需要删除目录里的celerybeat.pid文件，我试了一下，把他删掉了

 

竟然跑通了（他喵的
