执行git checkout时brew更新失败

Question

brew update由于网络问题而中断后,Homebrew似乎被破坏了:

$ brew update
error: pathspec 'master' did not match any file(s) known to git.
Error: Failure while executing: git checkout -q master 

查看/usr/localGit存储库,没有远程存储库.

$ cd `brew --prefix`
$ git remote -v
$

Answer 1

使用以下命令修复:

$ cd `brew --prefix`
$ git remote add origin https://github.com/Homebrew/homebrew.git
$ git fetch origin
$ git reset --hard origin/master
$ brew update
Already up-to-date.
