Flask - Deployment

You run uwsgi --http :5000 --module app:app but get an error saying the module 'app' cannot be found. What is the most likely cause?

AThe app.py file is missing or not in the current directory

BThe uWSGI command requires the --wsgi-file option instead of --module

CThe port 5000 is already in use by another process

DThe Flask app is not installed properly

Step-by-Step Solution

Solution:

Step 1: Understand module loading in uWSGI
Using --module expects a Python module named 'app' with an 'app' variable inside.
Step 2: Check file presence and location
If 'app.py' is missing or not in the current directory, uWSGI cannot find the module.
Final Answer:
The app.py file is missing or not in the current directory -> Option A
Quick Check:
Missing app.py causes module not found error [OK]

Quick Trick: Check app.py file exists in current folder [OK]
