git - Lion OS - brew 更新返回 "Failure while executing..."

Question

当我设置时，我正在尝试更新我的 brew

brew update

我收到这个错误:

error: Your local changes to the following files would be overwritten by merge:
    Library/Formula/imagemagick.rb
Please, commit your changes or stash them before you can merge.
Aborting
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

或

error: The requested URL returned error: 403 while accessing https://github.com/mxcl/homebrew/info/refs
fatal: HTTP request failed
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

Git 有什么问题？如果这种方式不起作用，如何更新 brew？

Answer 1

这是由 update 代码中的一个旧错误引起的，该错误早已被修复。但是，错误的性质要求您执行以下操作:

cd $(brew --repository)
git reset --hard FETCH_HEAD

如果 brew doctor 仍然提示未提交的修改，也运行此命令:

cd $(brew --repository)    
git clean -fd
