最近 brew 的提示，搞不懂啊。。

[uuair]

brew 更新的时候，提示是这个：

Ignoring path homebrew-cask/
To restore the stashed changes to /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask run:
  'cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask && git stash pop'
Updated 2 taps (homebrew/core and homebrew/cask).
==> Updated Formulae

我一看，提示的还挺详细，那么就继续呗：

cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask && git stash pop
Already up to date!
On branch master
Your branch is up to date with 'origin/master'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)

	homebrew-cask/

nothing added to commit but untracked files present (use "git add" to track)
Dropped refs/stash@{0} (7f413ded69914ef213d6e822b4679367d2c7c46e)  

然后捏？？？？怎么不对啊。。。

是不是多了个目录： /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask/homebrew-cask/
猜的

我也一直遇到这个问题，执行了那条命令后可能会修复，但过一段时间又出现。
没改过那些文件，但有次 git clone 下来，查找一个软件历史版本安装过。

建议:

cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask
git add . -A
git stash
git stash drop
git reset --hard origin/master

如果自己没动过那目录的话 应该可以删除然后重新 tap 一下

@Lax #1 没有啊。。


@yuikns #3 我试了一下，并没有解决，还是老样子。。


@wd #4 只好如此了，我回头试试

如果没使用 brew-cask，则直接把 /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask 这个目录删除即可。

试下 brew update-reset

[isteveyang]

cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask && git stash pop

如果出现
.DS_Store already exists, no checkout
error: could not restore untracked files from stash
The stash entry is kept in case you need it again.

那就是.DS_Store 一开始没被 ignore 的问题，直接
git stash && git clean -d -f

就 OK 了
