J'ai du mal à utiliser pip pour installer presque tout. Je suis nouveau dans le codage, alors j'ai pensé que c'était peut-être quelque chose que je faisais mal et j'ai opté pour easy_install pour obtenir la plupart de ce dont j'avais besoin, ce qui a généralement fonctionné. Cependant, maintenant j'essaie de télécharger la bibliothèque nltk, et aucun des deux n'arrive à faire le travail.
J'ai essayé d'entrer
sudo pip install nltk
mais a obtenu la réponse suivante :

--easy_install installed fragments of the library and the code ran into trouble very quickly upon trying to run it.
Des idées sur cette question ? J'apprécierais vraiment un retour sur la façon dont je peux soit faire fonctionner pip, soit contourner le problème en attendant.
