trying to do your flask tutorial

[gswscreagle]

was trying to do your flask tutorial and it's not working for me...not sure why. This is what I was getting when trying to fire it up

gwilliams@alice:~/src/docker-curriculum/flask-app$ sudo docker run -p 8888:5000 gswscreagle/catnip Traceback (most recent call last): File "/usr/src/app/./app.py", line 1, in from flask import Flask, render_template File "/usr/local/lib/python3.10/site-packages/flask/init.py", line 21, in from .app import Flask, Request, Response File "/usr/local/lib/python3.10/site-packages/flask/app.py", line 34, in from .sessions import SecureCookieSessionInterface File "/usr/local/lib/python3.10/site-packages/flask/sessions.py", line 14, in from collections import MutableMapping ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/local/lib/python3.10/collections/init.py)

Hello, just change python version on your Dockerfile. FROM python:3.9 worked fine for me)

you can change requirements.txt to

Flask==2.0
itsdangerous==2.0.1
