Error: undefined method `desc' for Zlib:Class

я узнал, что это может быть проблемой обновления, поэтому я попытался обновления заваривания

Warning: Your Homebrew is outdated. 
You haven't updated for at least 24 hours. This is a long time in brewland! 
To update Homebrew, run `brew update`. 

Я вижу некоторые redundancys, но я не знаю, что делать с ними.

Убедитесь, что все под /usr/local принадлежит к группе admin:

chgrp -R admin /usr/local 
chmod -R g+w /usr/local 

Allow любой из группы admin, чтобы написать что-нибудь в /usr/local

chgrp -R admin /Library/Caches/Homebrew 
chmod -R g+w /Library/Caches/Homebrew 

Неопределенный метод desc означает, что ваш Homebrew является устарели. После того как вы измените разрешения, попробуйте снова запустить brew update.
