Depuis la mise à jour MacOS Monterey (v12+) et pour toutes les versions à venir, Apple ne fournit plus de binaire PHP installé par défaut.

Si vous utilisez composer par exemple pour l’un de vos scripts ou plugin, voici le message d’erreur que vous pouvez obtenir:

composer update --no-plugins --no-scripts
env: php: No such file or directory

J’ai tenté pas mal de solutions, comme installer PHP avec brew mais cela n’a pas résolu le problème.

La véritable solution, toute simple finalement, est de réinstaller composer, qui se charge alors d’installer la version idoine de PHP.

Installer composer sous MacOS Monterey

On installe composer avec brew:

brew install composer

To force the link and overwrite all conflicting files:
  brew link --overwrite composer

To list all files that would be deleted:
  brew link --overwrite --dry-run composer

Comme vous pouvez le constater dans les résultats précédents, le lien symbolique n’a pas été créé correctement donc nous allons le corriger à la main.

On teste notre commande avec --dr-run d’abord:

brew link --overwrite --dry-run composer
Would remove:
/usr/local/bin/composer

Tout semble bon, on crée le lien symbolique:

brew link --overwrite composer
Linking /usr/local/Cellar/composer/2.1.14... 1 symlinks created.

On reteste maintenant notre mise à jour de plugin via composer:

composer update --no-plugins --no-scripts

Impeccable, composer et php sont de nouveau opérationnels sous Monterey.
