Windows 10 Home Python 3.8.1 Django 3.0.7
Lorsque j'installe le mysqlclient recommandé pour Django 2.2 et supérieur, j'obtiens la longue erreur suivante:
(venv) C:\Development\django-project\django_project>pip install mysqlclient

[Télécharger] et installer le fichier whl qui convient à votre environnement (https://www.lfd.uci.edu/~gohlke/pythonlibs/#mysqlclient)
Dans mon cas, c'était mysqlclient- 1.4.6-cp38-cp38-win32.whl.
Accédez au répertoire téléchargé et exécutez la commande suivante
python
(venv) C:\Development\django-project>pip install mysqlclient-1.4.6-cp38-cp38-win32.whl
Processing c:\development\django-project\mysqlclient-1.4.6-cp38-cp38-win32.whl
Installing collected packages: mysqlclient
Successfully installed mysqlclient-1.4.6
(venv) C:\Development\django-project>pip install mysqlclient
Requirement already satisfied: mysqlclient in c:\development\django-project\venv\lib\site-packages (1.4.6)
Maintenant que l'installation est terminée, installez-le avec pip install mysqlclient et il dira qu'il est déjà là.
