WSGIServer 出现“0.0.0.0”错误 - 需要整数（获取字节类型）

Question

我正在WSGIServer使用地址运行'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()

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

如果我改变'0.0.0.0'一切'127.0.0.1'都很好。

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 与 Python 3.8 不兼容。请在 Python 3.8 上使用 gevent >= 1.5a2。这是在 Python 3.8 上运行 gevent 1.4 的（几个）已知问题之一。
