Virtualenv: L'amorçage de données d'application s'interrompt avec de longs chemins sous Windows

Cela arrive-t-il toujours si vous transmettez --clear-app-data , par https://virtualenv.pypa.io/en/latest/cli_interface.html#clear -app-data ?

Merci pour l'astuce.

j'obtiens toujours une nouvelle erreur :

J'obtiens toujours la même erreur à cause du

Il semble que le chemin devienne trop grand pour Windows https://bugs.python.org/issue10447

Le chemin qu'il essaie d'écrire est :
C:\\Users\\runge\\AppData\\Local\\Packages\\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\\LocalCache\\Local\\pypa\\virtualenv\\seed-app-data\\v1.0.1\\3.8\\image\\CopyPipInstall\\pip-20.0.2-py2.py3-none-any\\pip\\_vendor\\urllib3\\packages\\ssl_match_hostname\\_implementation.py ; c'est 261 caractères qui vont facilement sur la prise en charge de 256 Windows.

Y a-t-il une solution à cela ?
Parce que je n'ai aucun contrôle sur les chemins

Modifiez le dossier de données de l'application via le drapeau ou utilisez le semoir à pépins en attendant

voir https://virtualenv.pypa.io/en/latest/cli_interface.html#app -data qui permet de changer le chemin temporaire 👍

Merci beaucoup. Cela fonctionne maintenant en changeant le dossier de données de l'application 👍

Soit dit en passant, vous pouvez également activer les longs chemins par https://www.howtogeek.com/266621/how-to-make-windows-10-accept-file-paths-over-260-characters/

Un ouais.. tu as raison. Cette option a été activée dans moi précédemment la configuration du système d'exploitation. Merci pour l'astuce.
Pas étonnant que cela soit passé avant.

Je pense qu'un avertissement si les longs chemins sont désactivés est utile

Je ne connais pas de moyen bon marché de vérifier ça (ou même un moyen coûteux) 🤔 En connaissez-vous ?

Si une erreur se produit, comptez la longueur du dernier chemin et si la longueur est supérieure à 260 caractères, affichez un avertissement pour vérifier le paramètre de long chemin.

Pensez que c'est la solution la plus rapide et la plus simple.

Cela peut arriver dans au moins 3 autres endroits. Comment faites-vous la différence entre un chemin qui n'existe pas et un chemin trop long, et qu'en est-il du chemin qui est trop long et qui n'existe pas non plus ?

D'accord c'est vraiment difficile🤔

Créer un chemin tmp en cascade aléatoire supérieur à 260 , si une condition d'augmentation se produit, la limite de chemin est définie

À propos, vous pouvez également activer les longs chemins par howtogeek.com/266621/how-to-make-windows-10-accept-file-paths-over-260-characters

Je vais fermer cela pour le moment car cela ne résoudra pas, et encouragerai plutôt les gens à utiliser la solution de contournement ci-dessus. Si plus de personnes rencontrent cela, nous pouvons y remédier, mais compte tenu du nombre de personnes qui ont signalé cela/ont rencontré cela, je considère que cela ne vaut pas encore la peine.
