In an attempt to obtain hot reload in Python 3.8 on Windows 10, I'm running:
from flask import Flask
from livereload import Server
if __name__ == '__main__':
flask_app = Flask(__name__)
server = Server(flask_app.wsgi_app)
server.serve() # Why NotImplementedError here?
But getting a NotImplementedError at server.serve(). Googling/SO-crawling/... wasn't beneficial.
Why is it happening? how do I fix it?
More Info:
