Replit运行Flask-SocketIO报错OSError: protocol not found求助

我是Flask和SocketIO的新手，目前在Replit平台运行代码。当导入flask_socketio（代码第2行）时，会触发OSError: protocol not found错误。我想要实现的功能是：点击网页按钮后向服务器发送消息，服务器打印“Request Recieved!”。

以下是我的服务器代码、网页代码及报错日志，我已经尝试过安装相关依赖但问题仍未解决，希望能得到帮助。

服务器代码 #

from flask import *
from flask_socketio import *

app = Flask(__name__, template_folder = "templates", static_folder='static')
socketio = SocketIO(app)

@app.route("/")
def main_page():
  return render_template("main.html")

@socketio.on("buttonPressed")
def handleRequest():
  print("Request Recieved!")
  return ("", 204)

if __name__ == "__main__":
  app.run(host = "0.0.0.0", port = 2345)

网页代码 #

<html>
  <body>
    <h1>Request Testing</h1>
    <button onclick="testButton()">Test</button>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/4.0.1/socket.io.js" integrity="sha512-q/dWJ3kcmjBLU4Qc47E4A9kTB4m3wuTY7vkFJDTZKjTs8jhyGQnaUrxa0Ytd0ssMZhbNua9hE+E7Qv1j+DyZwA==" crossorigin="anonymous"></script>
    <script>
      var socket = io();
      
      function testButton() {
        socket.emit("buttonPressed");
      }
    </script>
  </body>
</html>
