ModuleNotFoundError: No module named 'app' on new Django installation-CodePudding

I am trying to set up a simple Django==4.0.6 dev environment on my Ubuntu 20.04. I'm creating a project folder, create and activate a venv first. Then I'm installing Dajngo using pip. I'm then creating a new project in the very same directory and then for testing this out, run the usual python manage.py command. Here's a quick list of commands I am using:

mkdir project && cd project
python3 -m venv venv
source venv/bin/activate
pip install django==4.0.6
django-admin startproject major .
python manage.py migrate

But I'm getting the following error:

ModuleNotFoundError: No module named 'app'

I wasn't able to find a similar case where someone got the same error using a plain new installation in a virtual environment.

I haven't modified any files in the installation, fresh installation only. I was wondering if this has to do anything with my non-env Python. But I couldn't figure out what it is following the traceback.

Update:

I have tested this on every other machine and it works fine as it is a simple installation process for any Django project.

CodePudding user response：

Moving to an answer instead of a comment - is your $DJANGO_SETTINGS_MODULE environment variable set to something with app in it by any chance?

To fix, unset that environment variable.

CodePudding user response：

if you created folder 'app' manually and there don't exists _ _ init _ _.py - you receive those Error.
