问题 I have uninstalled and installed Homebrew 3 times now because it seems to never allow me to install anything as it denies me permissions at the end of most installations. As an example I will post this libjpeg download scenario that I\'m currently facing. I try to install libjpeg and get: $ brew install libjpeg ==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/jpeg-8d.mountain_lion.bottle.1.tar.gz Already downloaded: /Library/Caches/Homebrew/jpeg-8d.mountain_lion.bottle.1
