在Python中，Spyne有很多问题

Question

下面是我的Python代码：

#!/usr/bin/env python
from spyne import Application, rpc, ServiceBase, Unicode
from lxml import etree
from spyne.protocol.soap import Soap11
from spyne.server.wsgi import WsgiApplication
# Wsgi это Web server Getewap Interface - стандар взаимодействия с питон программой и серверо где он работает

class Soap(ServiceBase):
    @rpc(Unicode, _return=Unicode)
    def Insoap(ctx, words):
        print("Connection detected: ", etree.tostring(ctx.in_document))
        ww = str(words).capitalize()
        return ww

app = Application([Soap], tns='Capitalize', in_protocol=Soap11(validator='lxml'), out_protocol=Soap11())
application = WsgiApplication(app) # Важна названия переменной, иначе сервер не поймет


if __name__ == '__main__':
    from wsgiref.simple_server import make_server
    server = make_server('localhost', 8002, application)
    server.serve_forever()

但是如果有这个错误，有什么问题吗？我该怎么做才能解决这个问题？请帮我解决这个问题

async是Python中的一个保留关键字，如果您想在Python中使用它，您需要使用最新版本的Spyne，它在函数中不使用保留关键字作为参数。

要么将Spyne更新为spyne-2.13.2-alpha，要么使用Python 3.6或更低版本。
