Virtualenv: Virtualenv ne peut pas copier la bibliothèque intégrée

Créé le 9 déc. 2020  ·  8Commentaires  ·  Source: pypa/virtualenv

Problème

J'ai créé un environnement virtuel, le répertoire / lib / Python n'a pas de bibliothèques intégrées (uniquement site-Package).
Parce que je vais l'utiliser.

Environnement
python: 3.8.1
Fournissez au moins:

  • Système d'exploitation: Centos7.8
  • pip list du python hôte où virtualenv est installé:

Sortie de la création de l'environnement virtuel

Assurez-vous d'exécuter la création avec -vvv --with-traceback :

Il ne copiait qu'une partie des packages intégrés, et c'était uniquement pour python 2.

J'ai créé un environnement virtuel, le répertoire / lib / Python n'a pas de bibliothèques intégrées (uniquement site-Package).
Parce que je vais l'utiliser.

C'est par conception. Vous aurez probablement besoin de développer davantage sur la façon dont vous souhaitez l'utiliser et pourquoi.

Maintenant, il y a un problème.

Je sais que je ne devrais probablement pas poser de questions ici, mais je ne sais vraiment pas où aller, alors je suis désolé.

Veuillez fournir un guide détaillé étape par étape sur la façon dont vous y êtes arrivé. Idéalement une image de docker.

  1. Compiler python381
  2. Installez pip virtualenv
  3. Créer un environnement virtuel ./virtualenv -vvv --always-copy --clear / opt / env_test
  4. Copiez le fichier libpython3.8.so.1.0 dans / opt / env_test / lib
  5. Compresser / opt / env_test
  6. scp sur une autre machine et décompresser
  7. Définissez LD_LIBRARY_PATH sur libpython3.8.so.1.0
  8. / env_test / bin / python3

Les environnements virtuels sont des références aux pythons globaux et ne sont pas destinés à vivre seuls. Ils ne sont pas destinés à être copiés sur une autre machine. Et ils ne fonctionneront que si vous copiez également le python global et créez l'environnement virtuel en mode copie. Voir https://www.youtube.com/watch?v=o1Vue9CWRxU

Thx, la vidéo a résolu mon problème.
