OS X 中的 brew 更新

Question

我正在尝试在 OS X El Capitan 10.11.3 中安装 brew 但我收到了这个错误：

MacBook-Pro-de-paquirrin:~ paquirrin$ sudo brew update
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- mach (LoadError)

Answer 1

问题来自目录 /usr/local 的所有者。仅此而已，命令 sudo chown $(whoami):admin /usr/local 就足够了（没有 -R）

我按照这些说明成功了：https://github.com/Homebrew/legacy-homebrew/issues/49879

总结这两个命令：

sudo chown -R $(whoami):admin /usr/local
cd $(brew --prefix) && git fetch origin && git reset --hard origin/master

应该修复它。
