osx-mountain-lion - 为什么 brew doctor 在 mdfind 上拖延？

Question

问题

我一直有 Homebrew 软件的问题，所以我想我应该运行 brew doctor ，但它只是在 mdfind 上停滞不前。 brew --config输出以下内容后也卡在 mdfind 上:

HOMEBREW_VERSION: 0.9.4
ORIGIN: https://github.com/mxcl/homebrew
HEAD: c2cc58163b54a9ea2ee56febfc722396079c5b9a
HOMEBREW_PREFIX: /usr/local
HOMEBREW_CELLAR: /usr/local/Cellar
CPU: quad-core 64-bit sandybridge
OS X: 10.8.3-x86_64
Xcode: 4.6.2
CLT: 4.6.0.0.1.1365549073
LLVM-GCC: build 2336
Clang: 4.2 build 425

brew update似乎工作:

$ brew update
Already up-to-date.

我什至可以安装东西:

$ brew install rsnapshot
==> Downloading http://rsnapshot.org/downloads/rsnapshot-1.3.1.tar.gz
######################################################################## 100.0%
==> ./configure --prefix=/usr/local/Cellar/rsnapshot/1.3.1 --mandir=/usr/local/C
==> make install
🍺  /usr/local/Cellar/rsnapshot/1.3.1: 12 files, 356K, built in 4 seconds

他们甚至可以工作:

$ rsnapshot
rsnapshot 1.3.1
Usage: rsnapshot [-vtxqVD] [-c cfgfile] [command] [args]
Type "rsnapshot help" or "man rsnapshot" for more information.  

我试过的

卸载所有软件包

解锁所有小桶

重新安装 Homebrew 软件

重新安装 XCode + 命令行工具

安装 XQuartz(我必须通过命令行完成)

使用 Spotlight 重新索引我的系统驱动器

重置 xcode-select 路径

删除 /usr/share/xcode-select/

解决方法

运行后 brew doctor , 如果我两次终止 mdfind 进程(一个实例在另一个终止后产生)，我最终会得到一个成功的返回:

$ brew doctor
Your system is ready to brew.

同样处理配置:

$ brew --config
OMEBREW_VERSION: 0.9.4
ORIGIN: https://github.com/mxcl/homebrew
HEAD: c2cc58163b54a9ea2ee56febfc722396079c5b9a
HOMEBREW_PREFIX: /usr/local
HOMEBREW_CELLAR: /usr/local/Cellar
CPU: quad-core 64-bit sandybridge
OS X: 10.8.3-x86_64
Xcode: 4.6.2
CLT: 4.6.0.0.1.1365549073
LLVM-GCC: build 2336
Clang: 4.2 build 425
X11: 2.7.4 => /opt/X11
System Ruby: 1.8.7-358
Perl: /usr/bin/perl
Python: /usr/bin/python
Ruby: /usr/bin/ruby => /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

请注意配置中的下一项，在通常的停顿点之后，是 X11。

更多信息

我最近不得不从我的系统中删除手动编译的 ICU 版本，而且我实际上删除了一些 ICU 未安装的二进制文件的可能性很小。我不确定，但我想我会提到它以防万一。即使确实让我听起来很傻。
brew doctor终止时没有输出。
brew doctor似乎在 check_for_latest_xquartz 上拖延了特别检查，我已经检查过:

$ brew doctor check_for_latest_xquartz

我的 xcode-select路径似乎正确:

$ xcode-select --print-path
/Applications/Xcode.app/Contents/Developer

mdfind可以找到XQuartz:

$ mdfind "kMDItemCFBundleIdentifier == 'org.macosforge.xquartz.X11'"
/Applications/Utilities/XQuartz.app

......但它仍然没有返回。

Answer 1

您 GitHub 链接中的最后一篇文章似乎回答了这个问题:

This is by far the most useful thread on this very frustrating topic. I tried everything above and found that brew doctor hung on:

check_for_autoconf (kill mdfind 2x)
check_for_latest_xquartz (kill mdfind 2x)
check_for_linked_keg_only_brews (kill mdfind 4x)
check_for_osx_gcc_installer (kill mdfind 2x)
check_for_stray_developer_directory (kill mdfind 2x)
check_missing_deps (kill mdfind 2x)
check_standard_compilers (kill mdfind 1x)
Note that killing mdfind multiple times at least allows brew doctor to continue but that is not a solution.

When brew doctor finally completed, I noticed one warning:

check_user_path_2
Warning: Homebrew's bin was not found in your PATH.
Consider setting the PATH for example like so
    echo export PATH='/usr/local/bin:$PATH' >> ~/.bash_profile

This added export PATH=/usr/local/bin:$PATH to ~/.bash_profile. This was also at the beginning of ~/.bash_profile and twice at the end so I deleted all but the last statement. Opening a new terminal window, now /usr/local/bin is at the beginning of my path instead of in the middle.

Now brew doctor runs without hanging!

如果这不能解决问题，我建议在 GitHub 上为这个线程做贡献或在 GitHub 上打开一个新问题，因为它可能是 homebrew 中的一个错误。
