Homebrew升级修复
在升级git成2.9的时候，终于遇到了之前升级时Homebrew的坑，于是只好一个个来修复。
执行：
brew doctor
返回了一系列很长的日志，于是便保存了日志，然后一个个处理。
nohup brew doctor > log.log
第一个问题比较简单，并且也有一个相对简单的解决方案，即: brew prune
Warning: Broken symlinks were found.Remove them with `brew prune`:
/usr/local/bin/2to3-3.4
/usr/local/bin/N1
/usr/local/bin/TexturePacker
/usr/local/bin/aclocal
/usr/local/bin/aclocal-1.14
/usr/local/bin/automake
于是，便执行了这个命令：
brew prune
然后遇到了权限问题：
Error: Permission denied - /usr/local/share/ghostscript/9.16/Resource/CIDFont/HiraKakuPro-W3
就可以用下面的命令来解决这个问题了：
sudo chown -R "$USER":admin /usr/local
随后，终于成功修复了第一个问题。
Pruned 484 symbolic links and 317 directories from /usr/local
接着，遇到一系列的多出来的库的问题：
Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.
Unexpected dylibs:
/usr/local/lib/libffi.6.dylib
/usr/local/lib/libjlinkpic32.4.90.1.dylib
/usr/local/lib/libmcrypt.4.4.8.dylib
删除之：
rm /usr/local/lib/libmcrypt.4.4.8.dylib
以及多出来的头文件：
Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.
Unexpected header files:
/usr/local/include/Extras/OVR_Math.h
/usr/local/include/Kernel/OVR_Alg.h
/usr/local/include/Kernel/OVR_Allocator.h
接着就是修复一些没有link的库的问题了：
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
binutils
erlang
gcc
gnutls
brew link binutils
Linking /usr/local/Cellar/binutils/2.25.1...
Error: Could not symlink share/info/bfd.info
Target /usr/local/share/info/bfd.info
is a symlink belonging to gdb. You can unlink it:
brew unlink gdb
To force the link and overwrite all conflicting files:
brew link --overwrite binutils
To list all files that would be deleted:
brew link --overwrite --dry-run binutils
重新安装之：
brew uninstall binutils
brew install binutils
还有一个更有意思的问题，这时候只好一个个的将这些第三方库清空：
Error: uninitialized constant AbstractPhpVersion::Php70Defs
Please report this bug:
https://git.io/brew-troubleshooting
/usr/local/Library/Taps/homebrew/homebrew-php/Abstract/abstract-php-extension.rb:216:in `<class:AbstractPhp70Extension>'
/usr/local/Library/Taps/homebrew/homebrew-php/Abstract/abstract-php-extension.rb:215:in `<top (required)>'
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in
先删了再说：
rm -rf /usr/local/Library/Taps/josegonzalez/homebrew-php
还有需要安装的依赖
Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:
brew install docker-machine hicolor-icon-theme ocaml qt qt5
不需要的依赖：
You may wish to `brew unlink` these brews:
libxml2
libxslt
openssl
homebrew/versions/tomcat6
以及一些配置问题——即在$PATH后面多了一个"/"
Warning: Some directories in your path end in a slash.
Directories in your path should not end in a slash. This can break other
doctor checks. The following directories should be edited:
/Users/fdhuang/gocode/bin/
/usr/local/sbin/
/usr/local/gcc_arm/gcc-arm-none-eabi-4_8-2014q3/bin/
/Library/TeX/texbin/
然后执行
brew update
