当运行brew医生或brew -config时，国产brew冻结。

Question

几天前，当我尝试运行brew doctor或brew --config时，自制软件开始卡住了。产出如下：

$ brew --config
HOMEBREW_VERSION: 0.9.5
ORIGIN: https://github.com/Homebrew/homebrew.git
HEAD: 391ed374442cb8f91d9168ccd23f1c97b84686d1
Last commit: 6 minutes ago
HOMEBREW_PREFIX: /usr/local
HOMEBREW_CELLAR: /usr/local/Cellar
CPU: quad-core 64-bit sandybridge
OS X: 10.10.1-x86_64

和

$ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Setting DYLD_* vars can break dynamic linking.
Set variables:
    DYLD_LIBRARY_PATH: /usr/local/kde4/lib:/Users/<username>/Desktop/anderes/benvium-libimobiledevice-macosx-8507dd2

退出的唯一方法是向进程发送一个SIGINT。总之，brew update起了作用：

$ brew update
Updated Homebrew from cd9895d9 to 391ed374.
==> Updated Formulae
curl         fwknop   john-jumbo   sshrc
$ brew update
Already up-to-date.

我尝试过重新安装自制，但它似乎不起作用：

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
It appears Homebrew is already installed. If your intent is to reinstall you
should do the following before running this installer again:
    rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
$ rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
/Users/<username>/.rbenv/shims/ruby: line 21: /usr/local/Cellar/rbenv/0.4.0/libexec/rbenv: No such file or directory

令人惊讶的是，brew命令本身即使在上面的rm命令之后也能工作。我在想我做错了什么。谢谢你的帮助！

我现在有了一个解决方案: xcode-select指向错误的目录。sudo xcode-select -switch /Applications/Xcode.app解决了这个问题。
