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

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.
