Homebrew update error not work on OSX

brew update 错误是这样的

chown: /usr/local: Operation not permitted

然后网上osx 10.11, 10.12的解决方法这样的

The problem mainly occurs after updating OS X to El Capitan (OS X 10.11) or macOS Sierra (macOS 10.12). This is mainly because of file permission issues with El Capitan’s or later macOS's new SIP process. Try changing permissions of /usr/local directory.

$ sudo chown -R $(whoami):admin /usr/local

If it still doesn't work, use following steps and everything will be fine. This may be because homebrew is not updated.

. open terminal

. $ cd /usr/local/Library/Homebrew

. $ git reset --hard

. $ git clean -df

. $ brew update

10.13之后库克怒了,不管你怎么执行命令都不让你运行哪怕是root ,所以有人这么干:

看来只有关掉SIP了

.重启Mac，按住Command + R键直到Apple Logo出现，进入Recovery Mode模式（我感觉我是按了好半天）

.点击工具里的Terminal（终端）

.输入csrutil disable，之后回车

.重启Mac

.重启完成后，终端中输入 sudo chflags norestricted /usr/local && sudo chown -R $(whoami):admin /usr/local

成功执行，没有报操作不允许了

（如果想重新开启安全设置，则重复1、2步骤，输入csrutil enable就可以了）

然而根本没这么麻烦这样就可以搞定 OS X 10.13 brew not work (简单的说就是卸载了再安装)

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)”

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
