Homebrew fatal：需要一次修改 (MacOs Sierra)

Question

不确定这个问题是否与升级到 MacOs Sierra 有关，但是从那一刻起，当我运行 'brew update'

→ brew update
Checking out v1.0.0 in /usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask...
To checkout master in /usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask run:

Did you intend to checkout 'refs/tags/1.0.0' which can not be resolved as commit?

我试过了运行宁

cd $(brew --prefix) && git fetch && git reset --hard origin/master

但它给了我这个错误：

fatal: Not a git repository (or any of the parent directories): .git

Answer 1

升级到 Sierra 后我遇到了同样的问题。

除了显示 Homebrew 安装路径的 brew --prefix 之外，还有显示 .git 目录所在位置的 brew --repository。

man brew 声称“对于标准安装，前缀和存储库是同一目录”。手册页已过时或我的安装不是“标准”，但我的 prefix 是 /usr/local 而我的 repository 是 /usr/local/Homebrew.

使用相同的命令但 cd $(brew --repository) 对我有用：

cd $(brew --repository) && git fetch && git reset --hard origin/master

Answer 2

已接受的答案对我不起作用。有效的方法是卸载 homebrew 并重新安装它：

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)"
brew analytics off

Answer 3

对我来说没什么用，我不得不求助于卸载并重新安装 Brew：

# change to home directory to avoid other errors later
cd ~

# uninstall brew
rm -rf /usr/local/Cellar /usr/local/.git && cd ~ && brew cleanup

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

Answer 4

卸载


/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

并重新安装。

Answer 5
