pylint-django shows error ModuleNotFoundError: No module named 'myproj'

Time:10-04

I have installed pylint and pylint-django. Then followed docs.

My django project is structured as follows:

/path/to/project/myproj/settings_test.py
/path/to/project/manage.py

Running the following command:

cd /path/to/project/
export DJANGO_SETTINGS_MODULE=myproj.settings_test
find . -name "*.py" | xargs pylint --load-plugins pylint_django --django-settings-module=myproj.settings_test

I face with this error: errors:

ModuleNotFoundError: No module named 'myproj'

Note: The following did not help:

python3 manage.py makemigrations
python3 manage.py migrate
pip install django-filter
touch __init__.py
export DJANGO_SETTINGS_MODULE=myproj

.

Steps for reproduction:

Note this is a MWE and getting around the problem will not fix it:

django-admin startproject myproj
cd myproj/
find . -name "*.py" | xargs pylint --load-plugins pylint_django # fine
export DJANGO_SETTINGS_MODULE=myproj.settings
find . -name "*.py" | xargs pylint --load-plugins pylint_django # error: ModuleNotFoundError: No module named 'myproj'

.

CodePudding user response:

Most likely your settings module is not on the Python import search path. To add it for the duration of the current session, run from inside your project directory:

export PYTHONPATH=$PYTHONPATH:$PWD

How to make this permanent is explained in this answer.
