Migration Django avec python3.6 ERREUR: root: code pour hash sha3_224 introuvable

Bonjour, j'ai lu Didacticiels Django et j'ai une erreur liée à la fonction de hachage sha3_224 au cours du processus de migration. Comment résoudre ce problème? Je vous remercie.

Cela a résolu mon problème:

cd /usr/bin
Sudo cp python3.6 python3

Auparavant, j'avais 3.6.2, après apt-upgrade, le système était en panne.

Vérifiez si votre python a été mis à jour récemment. Il se peut que le venv pointe du doigt l’ancien, en recréant ce qu’il a corrigé pour nous.

Exécuter mkvirtualenv venv ou virtualenv venv (en fonction de la manière dont vous l'avez créé) devrait également fonctionner tout en conservant les packages installés.

! Attention, il est vraiment correctif!

Ce problème apparaît dans la nouvelle version de python - 3.6.3.

La rétrogradation à 3.6.2 m'a aidé

Voici un PPA hérité: https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes/+index?batch=75&direction=backwards&start=75

Commandes pour les actions ultérieures de downgrading python:

Sudo apt install libpython3.6-minimal=3.6.2-1+xenial1 Sudo apt install python3.6-minimal=3.6.2-1+xenial1 Sudo apt install python3.6-stdlib=3.6.2-1+xenial1 Sudo apt install python3.6=3.6.2-1+xenial1

Cela m'est arrivé après la mise à niveau vers la version 3.6.3. Essayez de créer virtualenv avec Python 3.6.3 ou une version plus récente. Cela a résolu le problème pour moi.
