pip installer mysqlclient a échoué "Exécution de setup.py bdist_wheel pour mysqlclient ... error"

Question

J'essaie d'exécuter mon projet Python 3 sur mon Mac OS X High Sierra 10.13.4 nouvellement formaté, en exécutant d'abord pipenv install pour obtenir les dépendances, mais cela échoue.

Plus précisément, la partie où il ne parvient pas à installer les dépendances est la partie mysqlclient.

Ce message d'erreur apparaît:

_mysql.c:1894:3: error: use of undeclared identifier 'my_bool' my_bool recon = reconnect; ^ _mysql.c:1895:58: error: use of undeclared identifier 'recon' mysql_options(&self->connection, MYSQL_OPT_RECONNECT, &recon); ^

Je suis suffisamment frustré pour vouloir désinstaller toutes mes installations Python, mais j'ai bien peur de gâcher quelque chose avec Mac qui repose sur la version Python obsolète prédéfinie.

Comment puis-je installer mes dépendances correctement?

mysqlclient n'est pas compatible avec MySQL 8.0.11 au moment de l'écriture. Utiliser MySQL v5.7.x résoudra ce problème (du moins sur macOS).

Si vous obtenez cette erreur:

Construire des roues pour les paquets collectés: mysqlclient Lancez setup.py bdist_wheel pour mysqlclient ... erreur

Lors de l'installation de myclient à l'aide de pip, suivez les étapes ci-dessous:

Téléchargez miniconoda (de petite taille et contient les fichiers nécessaires)/anacondoa (all) Cliquez pour télécharger Miniconda
Installez-le
Vérifiez l'installation en utilisant commind "conda list" dans cmd
Exécutez cette commande ensuite, "conda install -c miniconda mysqlclient" c'est une autre façon d'installer mysqlclient

Une fois exécuté avec succès, puis relancez pip install mysqlclient, vous constaterez que votre sqlclient est déjà installé avec succès.

J'espère que cela résoudra votre problème. toujours pas s'il vous plaît partager les détails de l'erreur. J'aimerais aider.
