"AVERTISSEMENT : la valeur de schema.data ne correspond pas" lorsque j'essaie de mettre à jour pip ou d'installer des packages

Question

J'ai un Mac M1 et je viens de remarquer que lorsque j'essaie de mettre à niveau pip ou d'installer des packages, je reçois une série d'avertissements :

 user@mac01 ~ $python3 -m pip install --upgrade pip

S'il vous plaît donnez votre avis.

Answer 1

la rétrogradation vers une version antérieure de pip l'a corrigé pour moi :

python -m pip install pip==21.0.1

Answer 2

Pour ceux qui n'ont pas réussi à exécuter python -m pip install pip==21.0.1 (par exemple, a renvoyé le même message d'erreur comme ValueError: check_hostname requires server_hostname ), vous pouvez essayer de désactiver le proxy système et réessayer la commande (si vous utilisiez un proxy comme shadowsocks, v2ray, etc.).

Answer 3

As-tu essayé de l'exécuter depuis un environnement virtuel ?

 python3 -m venv venv
source ./venv/bin/activate
pip install --upgrade pip

Answer 4

Fait intéressant, pip se plaint même de lui-même :

 C:\python>python -m pip install --upgrade --force-reinstall pip
Collecting pip

Installing collected packages: pip
  Attempting uninstall: pip

    Uninstalling pip-21.1:

Vous pouvez supprimer les avertissements pédants en utilisant pip install foo 2>nul sous Windows ou pip install foo 2>/dev/null sous Linux. Cependant, soyez prévenu : cela supprimera également les erreurs importantes
