Heroku ---> Installation de pip remote: AttributeError: le module 'pip._vendor.requests' n'a pas d'attribut 'Session'

Une application Python 3.6 Django == 11 était en cours de déploiement et le code régulièrement poussé jusqu'à hier. Maintenant j'ai l'erreur:

remote: AttributeError: le module 'pip._vendor.requests' n'a pas d'attribut 'Session'

Comme je l’ai vu plus haut, OpenCv [cv2] n’est pas présent dans le répertoire de génération par défaut, par exemple. Je suis en train de déployer un buildpack Python OpenCV pour la même chose - mais il faut que ce problème soit résolu en premier

Je viens de rencontrer la même erreur:

AttributeError: module 'pip._vendor.requests' has no attribute 'Session'

Effacer le cache de construction Heroku a résolu le problème pour moi. Voici ce que vous devez faire:

  1. Installez le plugin officiel heroku-repo pour le CLI Heroku :

    $ heroku plugins:install heroku-repo

  2. Effacez le cache de construction de votre application:

    $ heroku repo:purge_cache -a APPNAME

  3. Déclencher un déploiement pour reconstruire votre application

Effacer le cache de construction amène pip à réinstaller entièrement vos dépendances Python lors de la prochaine construction au lieu de tenter de mettre à niveau votre ensemble de dépendances actuel.

Ceci a résolu la AttributeError pour moi, espérons que cela aide!

Pour me débarrasser de cela, je viens de changer from pip._vendor import requests en import requests

J'ai trouvé la solution ici: GitHub: AttributeError: le module 'pip._vendor.requests' n'a pas d'attribut 'Session' # 5267
