网上找答案是不兼容导致，需更新库：https://stackoverflow.com/questions/64105616/greenlet-runtime-error-and-deployed-app-in-docker-keeps-booting-all-the-workers

命令行执行pip3.exe list查看当前第三方库的版本

命令行执行pip3.exe install --upgrade gevent==20.9.0

然后问题解决，可以正常使用locust

附：

安装指定版本:pip3.exe install locustio==0.16.4

卸载pip3.exe uninstall locustio
