[FIXED] Python Flask socketIO server not running

Issue

I have this simple script with a Flask webserver. When I try to run the Python script, nothing happens, it just freezes.

I have already installed eventlet but this has not fixed the issue.

from flask import Flask, render_template
from flask_socketio import SocketIO

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


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


@socketio.event
def connect(sid, environ):
    print(sid, 'connected')


@socketio.event
def disconnect(sid):
    print(sid, 'disconnected')


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

How can I stop this script from freezing and make it serve the webpage?

Solution

I am not sure what you mean by 'it freezes' but if it means you don't get any output in the terminal for debugging, you can fix that by setting debug mode to true using:

socketio.run(app, debug=True)
