python-3.x - OSERROR：未找到协议

Question

我正在尝试构建一个 python 聊天应用程序，但在运行它时出现错误...

"/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.8/site-packages/dns/rdtypes/IN/WKS.py", line 25, in <module>
    _proto_tcp = socket.getprotobyname('tcp')
OSError: protocol not found

[Program finished]

蟒蛇程序：

from flask import Flask, render_template
from flask_socketio import SocketIO

app = Flask(__name__)
app.config['SECRET_KEY'] = 'secret!'
socketio = SocketIO(app)

if __name__ == '__main__':
    socketio.run(app)

如果你得到修复，请帮助我...
