Issue
I have a issue, problem is when I run flask app port :5000 it stops becouse: Port 5000 is in use by another program. Either identify and stop that program, or start the server with a different port. but I dont know when i use it. I change port by :
if __name__ == '__main__':
app.run(debug=True, host='0.0.0.0', port=8000)
but it doesnt change anything. also I use
export FLASK_APP=run.py
so I run app via flask run
Solution
There are a couple of options that might help.
If you are running your app using the flask run command in the terminal try adding this to the command
flask run -h localhost -p 8000
Another thing that might help is setting the run port in the environment variables like this
export FLASK_RUN_PORT=8000
Let me know if either of these work.
