ImportError: impossible d'importer le nom md5

Je ne sais pas vraiment ce qui se passe ici, j'ai besoin de déployer mon application flask sur élastique beanstalk, mais en quelque sorte changé le chemin et ne peut plus exécuter python application.py

J'ai déjà fait ces étapes aussi:

Vous avez toujours cette erreur:

Lorsque je fais [lien de brassage --force openssl], je reçois ci-dessous:

J'utilise macOS, corrigez cela en brew unlink openssl && brew reinstall python@2

J'utilise personnellement et recommanderais pyenv pour gérer les versions Python. Au début, je ne savais pas comment résoudre ce problème et j'ai essayé de réinstaller en utilisant brewcomme suggéré ici . Cependant, je me suis alors rappelé que j'avais l'habitude pyenvd'installer et j'ai donc pu corriger mon erreur avec.

pyenv install -f 2.7.15

L' -foption force l'installation de cette version même si elle existe déjà sur votre système. Vous auriez besoin d'utiliser2.7.16 ou quelle que soit la version que vous souhaitez utiliser.

Celui python-buildqui pyenvutilise utilisera la opensslbibliothèque brewsi elle est disponible.
