運行brew醫生或brew時自制軟件會凍結--config

Question

幾天前，當我嘗試運行brew doctor或brew --config時，自制軟件開始卡住了。輸出是：

$ 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 

退出正在發送一個SIGINT給進程的唯一途徑。無論如何，brew update工作：

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

我試過reinstalling homebrew，但似乎並沒有工作：

$ 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 

出人意料的是，BREW命令本身並甚至高於rm命令後。我想知道我做錯了什麼。謝謝你的幫助！

我現在得到了一個解決方案：xcode-select指向錯誤的目錄。 sudo xcode-select -switch /Applications/Xcode.app解決了這個問題。
