Comment supprimer proprement Homebrew

Comment puis-je supprimer proprement Homebrew. J'ai peut-être une ancienne installation défectueuse, et je voudrais avoir un nouveau départ.

Cela rm -rfne vous demandera pas si vous êtes sûr lorsque vous supprimez, alors assurez-vous que la cdcommande fonctionne pour vous sortir de / tmp (le cd /tmpvous emmène dans un endroit sûr au cas où vous copiez / collez tout en une seule fois afin de ne pas supprimer les fichiers de votre répertoire actuel)

Essayez ceci dans votre terminal:

cd /tmp
cd `brew --prefix`
rm -rf Cellar
brew prune
rm `git ls-files`
rm -r Library/Homebrew Library/Aliases Library/Formula Library/Contributions
rm -rf .git
rm -rf ~/Library/Caches/Homebrew

Plus d'informations sur ce sujet peuvent être trouvées dans la FAQ Homebrew .

Bien que l'installation de HomeBrew soit bien en vue sur sa première page, les détails ne le sont pas. https://brew.sh/ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" Pendant longtemps, il a été très difficile de trouver une désinstallation fiable. Maintenant, à quelques clics dans les documents, il existe maintenant une méthode officielle: https://docs.brew.sh/FAQ Pour désinstaller Homebrew, collez la commande ci-dessous dans une invite de terminal. ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
