flask socket io not working ( windows 7 & 10 ) anaconda and python 3.7

Question

I'm still a newbie in Development ( please don't rate down my post i've reached out everywhere to find a solution for the past 5 days ) , I had only two projects as a tutorial in the second project i had to use Socket IO with flask but its not working - if my code doesnt have socket io in it and i ran flask run it output the following :

D:\WORK\study sc5\project1\project1>flask run
Serving Flask app "hello"
Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

if it has socket io in it :

D:\WORK\study sc5\project2\project2>flask run
 * Serving Flask-SocketIO app "application"

**when i visited 127.0.0.1:5000 i found the server running so i ignored that it doesn't print Running on http://127.0.0.1:5000/ (Press CTRL+C to quit) and kept going tell i made the first test to see if socket io can print and i have noticed everything prints just fine but socket io

I've asked my class mates , made ticket on github for 5 days we couldn't solve this and i have tried on 2 machines ( home windows 10 and work place windows 7 ) both resulting the same thing

i made 2 videos about it ( i'll try to share them here if i'm allowed )

the .py files only have the following

import os

from flask import Flask
from flask_socketio import SocketIO, emit

app = Flask(__name__)
app.config["SECRET_KEY"] = "sdfsdfssefe"
socketio = SocketIO(app)


@app.route("/")
def index():
    return "Project 2: TODO"

---

systems i have this with 1- windows 10 - anacanda 2- windows 7 - anacanda

things i have tried so far :

• updating anaconda
• eventlet
• gevent
• uninstalling anaconda
• reinstalling a newer version of anaconda
• uninstalling anaconda again
• installing python 3.7

• installing all required to run project 1
  import os , passlib,requests

  from flask import Flask, session , render_template , request from

  flask_session import Session from sqlalchemy import create_engine

  from sqlalchemy.orm import scoped_session, sessionmaker from

  passlib.hash import sha256_crypt

• instaling eventlet with python 3.7

• installing cgywin
• testing server on cgywin

results all the same except

now after cgywin and python 3.7 when i tried to run my own version of project 2 which used to run smoothly but doesn't print anything from socket io - it now says ( can't import application.py )

I've open ticket on course group , github and videos to demonstrate what happens if anyone could explain how i can upload them i will do edit the post and share them

Answer 1

Does this work better?

import os

from flask import Flask
from flask_socketio import SocketIO, emit

@app.route("/")
def index():
    return "Project 2: TODO"

app = Flask(__name__)
app.config["SECRET_KEY"] = "sdfsdfssefe"
socketio = SocketIO(app)

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