Si quelqu'un pouvait m'aider, je l'apprécierais vraiment! Je soupçonne que le problème concerne plusieurs versions de python, mais je ne sais pas comment vérifier ou résoudre ce problème.

Il semble que vous rencontriez une erreur de permission basée sur ce message dans votre sortie: error: could not create '/lib/python2.7/site-packages/lxml': Permission denied.

Une chose que vous pouvez essayer est de faire installation par l'utilisateur du paquet avec pip install lxml --user. Pour plus d'informations sur son fonctionnement, consultez cette réponse StackOverflow . (Merci à Ishaan Taylor pour la suggestion)

Vous pouvez également exécuter pip install en tant que superutilisateur avec Sudo pip install lxml, mais ce n'est généralement pas une bonne idée car cela peut entraîner des problèmes avec vos packages au niveau système.

Mettre en place un virtualenv :

% curl -kLso /tmp/get-pip.py https://bootstrap.pypa.io/get-pip.py 
% Sudo python /tmp/get-pip.py

Ces commandes installent pip dans le répertoire global site-packages.

% Sudo pip install virtualenv

et idem pour virtualenv:

% mkdir -p ~/.virtualenvs

J'aime mes virtualenvs sous un arbre de mon répertoire personnel appelé .virtualenvs

% virtualenv ~/.virtualenvs/lxmltest

Crée un virtualenv.

% . ~/.virtualenvs/lxmltest/bin/activate

Supprime la nécessité de spécifier le chemin d'accès complet à pip/python dans ce virtualenv.

% pip install lxml

Vous pouvez également exécuter ~/.virtualenvs/lxmltest/bin/pip install lxml si vous avez choisi de ne pas suivre l'étape précédente. Notez que je ne suis pas sûr de votre progression, donc certaines de ces étapes peuvent être ignorées en toute sécurité. Bien sûr, si vous gâchez quelque chose, vous pouvez toujours rm -Rf ~/.virtualenvs/lxmltest et recommencer à partir d’un nouveau serveur virtuel.

Sur un Mac, vous devez utiliser cette commande:

STATIC_DEPS = true Sudo pip installer lxml
