Ошибка Ansible 2.x из-за изменений зависимостей paramiko 2.0

Question

Установка последней версии Ansible via pip завершилась неудачей из-за того, что paramiko 2.0 изменил свою зависимость от pycrypto до криптографии. Криптография имеет зависимость от cffi, для которой требуется libffi-dev. Кто-нибудь знает, как это исправить? (Ubuntu Trusty 14,04)

Answer 1

Чтобы установить cryptography >= 1.1 от ПУМ, вам необходимо установить пакет разработчика для libffi, поскольку он будет содержать отсутствующий файл заголовка. Поскольку вы отметили Ubuntu, я предполагаю, что вы используете диспетчер пакетов apt.

apt-get install libffi-dev

Вам также понадобится эквивалент вашего дистрибутива пакета разработки ssl «s и gcc для cryptography >= 1.1. Если вы запускаете это в своей системной среде, то gcc почти наверняка уже установлен, но вам может понадобиться и apt-get install libssl-dev, если этого не хватает.

Fedora/RHEL эквиваленты libffi-devel и openssl-devel, и может быть установлен с dnf или yum в зависимости от операционной системы и версии.

Answer 2

Найдено одно решение установить конкретные версии каждого:

pip install paramiko==1.17.0 ansible==2.0.0.2
