Ошибка при установке Python Plugin: ModuleNotFoundError: Нет модуля с именем <модуль>

Я пытаюсь создать Python-плагин для Saleor, используя Poetry, и у меня возникают проблемы с установкой плагина на Saleor. Я запускаю poetry add ../social_auth для установки плагина на Saleor, и это удается, но когда я пытаюсь запустить Saleor, я получаю эту ошибку:

No module named 'social_auth'

Но я проверил, модуль находится в settings.INSTALLED_APPS, settings.PLUGINS и перечислен в pip list...

Вот структура плагина:

├── __init__.py
├── poetry.lock
├── pyproject.toml
└── social_auth
    ├── __init__.py
    └── plugin.py

1 directory, 5 files

файл pyproject.toml:

[tool.poetry]
name = "social-auth"
version = "0.1.0"
description = "Social auth for saleor"
authors = ["Wellington Zenon <wellington.zenon@gmail.com>"]
packages = [
    { include = "plugin.py", from="social_auth"}
]

[tool.poetry.dependencies]
python = "^3.9"

[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"

[tool.poetry.plugins."saleor.plugins"]
"social_auth" = "social_auth.plugin:SocialLoginPlugin"

файл plugin.py:

Как я могу решить эту проблему?

PYTHONPATH=path/to/plugin
