Pb Pip installation version de package specifique

Je sou

    20 décembre 2021 à 13:00:16

    Bonjour, je suis débutant et actuellement entrains de faire le cours sur les packages python.

    Dans ce cours il m'est à un moment demandé d'installer scipy en version 1.5.1 

    Je fais donc la commande pip install scipy==1.5.1 et cela me renvois à un message d'erreur

    pourtant cette version existe bien j'ai vérifié 

    Cela me le fait même sur mon environnement global !

    je peux par contre installer la dernière version, mais lorsque j'essaye avec les anciennes versions cela me renvois un message d'erreur. 

    Et ça me le fait pour pratiquement chaque vieille version de package que je souhaite installer : 

    PS : j'ai python 3.9.9 et pip 21.2.4 

    L'erreur : 

    (env) E:\Mes documents\Formation Info\Python\Paquets pythons\projects\task_1>pip install scipy==1.5.1

      le message principal, je pense est celui-ci 

       error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/

      Donc en cliquant sur le lien, et installant l'outil, puis relançant l'installation de scipi, ça devrait un peu aller mieux

          Allez sur PyPI voir les versions de scipy disponibles, ce sont des binaires pré-compilés pour des versions >1.7.

          Pour une 1.5.1, il faut la reconstruire à partir des sources (et avoir VS studio qui fonctionne. Là où ça se corse, c'est que scipy dépend de tas de packages (et de tas de versions) qui ne seront pas plus disponibles.
