出现“0.0.0.0”错误的 WSGIServer - 需要一个整数（获得类型字节）

Question

我是运行 WSGIServer，地址 '0.0.0.0'

    from gevent import pywsgi
    from geventwebsocket.handler import WebSocketHandler

    server = pywsgi.WSGIServer(('0.0.0.0', 5002), app, handler_class=WebSocketHandler)

    server.serve_forever()

产生错误 TypeError: an integer is required (got type bytes)

如果我将 '0.0.0.0' 更改为 '127.0.0.1' 一切正常。

我在 MacOS 10.14.6

上使用 Python 3.8

这是完整的错误

根据 https://github.com/gevent/gevent/issues/1491:

gevent 1.4 is not compatible with Python 3.8. Please use gevent >= 1.5a2 on Python 3.8. This is one of the (several) known issues of running gevent 1.4 on Python 3.8.
