I have problems installing flask_socketio (when running flask, I get
"ModuleNotFoundError: No module named 'flask_socketio'"). I tried setting
FLASK_DEBUG=0 (apparently that worked for someone I read) and tried
uninstalling and re-installing (re-installing when installed just gives me
a bunch of "Requirement already satisfied"). I set up a brand new virtual
environment and if it helps below is my pip freeze and the complete error.
Am using python version 3.6.8. (Apologies- I'm a beginner,so maybe there is
too much or incomplete info..)
