Impossible d'installer via pip à cause de l'erreur egg_info

Question

Quel que soit le paquet que j'essaie d'installer, j'obtiens cette erreur :

error: invalid command 'egg_info'

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in c:\users\zorpix\appdata\local\temp\pip-build-Zorpix\virtualenv
Storing complete log in C:\Users\Zorpix\pip\pip.log

J'ai vu cette question mais la réponse ne fonctionne pas pour moi. Je peux installer le paquet distribute, qui jusqu'à présent est le seul paquet que je peux installer, mais cela ne résout pas le problème, car l'erreur egg_info revient dès que j'essaie d'installer un autre paquet. Je suis assez frustré par ce problème, car je ne trouve rien d'utile nulle part. J'avais également installé django, pip et tout le reste avant, mais j'ai dû tout réinstaller, et maintenant ça ne fonctionne plus... Toute aide serait appréciée.

Voici le journal qu'il dit avoir stocké :

Quel est ce setuptools qui me manque ?

Answer 1

J'ai trouvé ce qui n'allait pas. Je n'ai jamais installé les setuptools pour python, donc il manquait des fichiers vitaux, comme ceux de l'oeuf.

Si vous avez le même problème que moi, téléchargez ce fichier et ensuite dans powershell ou l'invite de commande, naviguez dans le répertoire de ez_setup et exécutez la commande et cela exécutera le fichier pour vous :

$ [sudo] python ez_setup.py

Si vous avez encore besoin d'installer pip à ce stade, exécutez :

$ [sudo] easy_install pip

easy_install faisait partie des setuptools, et ne fonctionnait donc pas pour installer pip.

Ensuite, pip installera avec succès django avec la commande :

$ [sudo] pip install django

J'espère avoir évité à quelqu'un le mal de tête que je me suis donné !

Answer 2

Essayez ça : pip install --upgrade setuptools o easy_install -U setuptools

Answer 3

Pour moi, la réinstallation puis la mise à jour du pip ont fonctionné.

1. Réinstaller pip en utilisant la commande ci-dessous ou le lien suivant Comment installer pip sur macOS ou OS X ?

   bouclette https://bootstrap.pypa.io/get-pip.py -o - | python

2. Mise à jour de pip après son installation

   pip install -U pip

Answer 4

Voir ce : Quelle version de Python puis-je utiliser avec Django ? https://docs.djangoproject.com/en/2.0/faq/install/

si vous utilisez python27, vous devez définir la version de django :

essayez : $pip install django==1.9

Answer 5

Ayant la même erreur en essayant d'installer matplotlib pour Python 3, ces solutions n'ont pas fonctionné pour moi. C'était juste une question de dépendances, bien que ce ne soit pas clair dans le message d'erreur.

J'ai utilisé sudo apt-get build-dep python3-matplotlib puis sudo pip3 install matplotlib et ça a marché.

J'espère que cela vous aidera !
