如果出错尝试下面这个方法(某高手分享，下面有原始连接)

Running Homebrew as root is extremely dangerous and no longer supported

解决方法

sudo chown -R `whoami` /usr/local/Homebrew/
$ sudo chown -R $(whoami) $(brew --prefix)/*
$ sudo mkdir /usr/local/Frameworks
$ sudo chown -R `whoami` /usr/local/Frameworks/

之后就可以了

sudo chmod  777 文件路径

切换 sudo

sudo su

sudo -i
