一，安装brew

1，安装brew

curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local —strip 1

2，安装完成后执行

brew

提示：Please run brew update!

3，按照提示更新，执行

brew update

报错：Error: /usr/local must be writable!

4，赋给/usr/local目录权限，执行sudo chown -R $(whoami) /usr/local，即

报错：Operation not permitted

发现是El Capitan（10.11） 加入了Rootless机制，很多系统目录不再能够随心所欲的读写了，即使设置 root 权限也不行。

以下路径无法写和执行

  1. /System
  2. /bin
  3. /sbin
  4. /usr (except /usr/local)
  • 1
  • 2
  • 3
  • 4

需要关闭rootless

如何关闭

重启按住 Command+R，进入恢复模式，打开Terminal

  1. csrutil disable
  • 1

sudo chown -R caositing /usr/local

其中caositing为系统当前用户名。

5，再次执行

brew update
