【问题描述】：

我正在尝试使用 gevent 使用 socket-io 执行烧瓶应用程序，但在启动时收到错误：

我的 uwsgi_conf.ini 很简单，只有这几行很重要：

http-websockets = true
http-socket = :1234
chmod-socket = 660
gevent = 1024

当我删除 gevent 行时，一切正常，没有 TypeError: 'module' object is not callable 错误

我在另一台服务器上也有这个项目的 1:1 副本，一切都运行良好

更新-1： gevent-early-monkey-patch = 1 如果我删除这一行，我会得到不同的错误：

Respawned uWSGI worker 1 (new pid: 26039)
DAMN ! worker 3 (pid: 26030) died :( trying respawn ...

标签： python sockets flask socket.io flask-socketio

【解决方案1】：

当我安装时 pip install gevent==1.4.0

一切都很完美，而不是新的一个 gevent 版本

【讨论】：

我还注意到最新的 gevent 在 Python 3.7 上运行良好，但在 3.8 上显示错误。
