Quand je lance la commande sur le site web de home brew,
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"J'ai compris :
==> This script will install:
/usr/local/bin/brew
/usr/local/Library/...
/usr/local/share/doc/homebrew
/usr/local/share/man/man1/brew.1
/usr/local/share/zsh/site-functions/_brew
/usr/local/etc/bash_completion.d/brew
==> The following directories will be made group writable:
/usr/local/.
==> The following directories will have their owner set to 17oei:
/usr/local/.
==> The following directories will have their group set to admin:
/usr/local/.
Press RETURN to continue or any other key to abort
==> /usr/bin/sudo /bin/chmod g+rwx /usr/local/.
chmod: Unable to change file mode on /usr/local/.: Operation not permitted
Failed during: /usr/bin/sudo /bin/chmod g+rwx /usr/local/.Cependant, je ne vois aucune raison à cela, car je suis un administrateur sur mon ordinateur.
Les drapeaux de fichier et l'ACL pour '/usr/local' (comme révélé par ls ) sont :
$ ls -lOed /usr/local
drwxr-xr-x 5 root wheel uchg 170 Aug 20 2015 local
