Ubuntu – Comment installer correctement la cryptographie en python 2.7.x (Ubuntu 14.04)? [fermé]

Je rencontre une erreur lorsque j’essaie d’exécuter pip install cryptography . Ceci sur Ubuntu 14.04 sur une gouttelette océanique numérique.

Je suis ce guide:

https://stackoverflow.com/a/29099439/515509

(Veuillez donc ne pas suggérer d’installer les mêmes packages répertoriés dans cette réponse – car je l’ai déjà fait :).

Ces packages sont: python-dev ,  libffi-dev et libssl-dev .

J’ai aussi installé pyOpenSSL ,  ndg-httpsclient et pyasn1 .

L’erreur que je reçois est la suivante (avertissement – c’est BEAUCOUP de texte:
