I build image via dockerfile

When container start i see error in container.

Traceback (most recent call last): File "./hello_app/init.py", line 1, in from flask import Flask # Import the Flask class ModuleNotFoundError: No module named 'flask' unable to load app 0 (mountpoint='') (callable not found or import error) no app loaded. GAME OVER

I know this is a year late but I just ran into this and resolved by changing the base image (which doesn't include flask) to:

tiangolo/uwsgi-nginx-flask:python3.8-alpine-2020-12-19

The issue seems happen again even "tiangolo/uwsgi-nginx-flask:python3.8-alpine-2020-12-19" is already changed to. It looks like the new image from Dockerhub was not built properly so Flask is not installed in. An easy way is just uncommenting below lines in Dockerfile:

COPY requirements.txt /

RUN pip install --no-cache-dir -U pip

RUN pip install --no-cache-dir -r /requirements.txt
