установка пакета pip на ПК, отключенном от интернета

Есть пакет pip в формате pyproject.toml, который я пытаюсь установить на машине отключенной от интернета:

./foo
├── pyproject.toml
└── src
    └── foo
        └── __init__.py

pyproject.toml:

#
[build-system]
build-backend = "setuptools.build_meta"
requires = ["setuptools>=61.0", "wheel>=0.37.1"]

[project]
name = "foo"
version = "1.0"

[tool.setuptools.packages.find]
namespaces = false
where = [ "src" ]

__init__.py :

#!python

def foo():
    return 42

Нужные пакеты на машине стоят:

~/test_env/bin/python -m pip list 
...
setuptools          68.2.2
wheel               0.41.3
...

При попытке установки получаю ошибку:

Если разрешаю обращаться к интернету, (через export https_proxy=...), то пакет успешно устанавливается, хотя setuptools и wheel при этом не обновляет.

Флаги pip --no-index --no-deps не меняют поведения.
