KeyError: 'Command line or configuration file'

[Tobi-De]

Hello, running the latest version of pylint and pylint-django fails with ModuleNotFoundError: No module named 'config' and KeyError: 'Command line or configuration file'.

This is very similar to #370

To reproduce the issue you can clone this repo https://github.com/Tobi-De/maskey
Create a virtualenv, install the requirements using the requirements.txt file and run pre-commit or just this command
pylint -rn -sn --rcfile=pyproject.toml --django-settings-module=config.settings .

Output of pip freeze

pylint==2.15.10
pylint-django==2.5.3

pyproject.toml

[tool.pylint.MASTER]
load-plugins = "pylint_django"
django-settings-module = "config.settings"pylint -rn -sn --rcfile=pyproject.toml --django-settings-module=config.settings  . 
ignore-paths = ".*/migrations"

This is not particularly relevant since the same thing happens when I run the command from the shell, but I'm adding it just in case.

pre-commit config

  - repo: local
    hooks:
      - id: pylint
        name: pylint
        entry: pylint
        language: system
        types: [ python ]
        args:
          [
            "-rn", # Only display messages
            "-sn", # Don't display the score
            "--rcfile=pyproject.toml"
          ]

This solution worked for me. Add this to your .pylintrc. This assumes your pylintrc is in the root directory of your project.

[MASTER]
init-hook="from pylint.config import find_pylintrc; import os, sys; sys.path.append(os.path.dirname(find_pylintrc()))"
