无论我设置哪个端口，Python都说它被使用我不明白为什么，我正在使用twisted
Sat Aug 26 12:49:31 2017 - (/usr/lib/python2.7/dist-packages/twisted/internet/tcp.py:980) Couldn't listen on any:4444: [Errno 98] Address already in use.

除了端口正在使用之外，我没有任何其他错误。 如果您需要整个服务器，请提供带requirements.txt的压缩文件

您要将服务器设置为两次监听 - 一次使用listenWS，一次使用reactor.listenTCP。删除reactor.listenTCP，您可以listenWS为您致电reactor.listenSSL。

这种情况可能有多种原因[一般解决方案]，
原因1：您可能尝试运行您的应用程序是其中一个保留端口[0-1024]，因此某些应用程序可能实际使用该端口。
原因2：您可能已终止该应用程序，因此从未调用关闭套接字的指令（例如socket.close（））。套接字在某处开放
原因3：这是您唯一的错误消息吗？它是否说明了管理员权限？您是否尝试过以管理员权限运行？
