Скачиваем, но не устанавливаем argon2-cffi

Question

Мы размещаем простой сервер Pypi в нашей компании.

Эта команда работает для большинства пакетов pip, но не работает для argon2-cffi:

pypi@pypihost:~> pip install  -d packages argon2-cffi

Command "python setup.py egg_info" failed with error code 1 in /home/pypi/tmp/pip-build-LJ1EjJ/argon2-cffi/

Я не хочу, чтобы gcc запускался в этом случае, так как я только хочу его скачать.

Что я делаю не так?

Я использую SuSE Linux 12.3

Большое "спасибо" Гинеку Шлаваку, он исправил эту проблему: https://github.com/hynek/argon2_cffi/issues/17

Теперь можно загрузить argon2_cffi без запуска процесса компиляции.
