#### 问题描述： ####

在进行brew update时，发生错误，如下：

> % brew update
> 
> fatal: Could not resolve HEAD to a revision
> 
> Already up-to-date.

#### 解决办法： ####

> 思路：
> 
> 1）找到出错的homebrew的目录；
> 
> 2） 进入到该目录，执行fetch 和 pull命令。

1）运行“brew update --verbose”，找到出错的homebrew的目录：

> **% brew update --verbose**
> 
> Checking if we need to fetch /usr/local/Homebrew...
> 
> Checking if we need to fetch /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask...
> 
> Checking if we need to fetch /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core...
> 
> Fetching /usr/local/Homebrew...
> 
> Updating /usr/local/Homebrew...
> 
> Branch 'master' set up to track remote branch 'master' from 'origin'.
> 
> Switched to and reset branch 'master'
> 
> Your branch is up to date with 'origin/master'.
> 
> Switched to and reset branch 'stable'
> 
> Current branch stable is up to date.
> 
> Updating /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core...
> 
> fatal: Could not resolve HEAD to a revision
> 
> Already up-to-date.

2）进入到出错的目录，然后先fetch，后pull，如下：

> cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
> 
> % pwd
> 
> /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
> 
> % **git fetch --prune origin**
> 
> % **git pull --rebase origin master**
> 
> From https://github.com/Homebrew/homebrew-core
> 
> \* branch master -> FETCH\_HEAD
> 
> Updating files: 100% (6435/6435), done.
