我很久以前就安装了 homebrew，但用得并不多，但我正在考虑重新开始使用它，因为它是一个非常有用且易于使用的软件包安装程序。不管怎样，我运行了brew doctor并收到了一大堆警告，我不知道如何解决！我特别害怕删除 .dylib、.la 和 .pc 文件，以防我的未通过自制程序安装的软件包需要它们。如果我运行的是 Mac OS X Mountain Lion (10.8.3)，对此问题的任何帮助将不胜感激，我的警告列表如下：
UOS-12044:~ as34g12$ brew doctor
Warning: /usr/local/include isn't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew.
If a brew tries to write a header file to this directory, the install will
fail during the link step.
You should probably `chown` /usr/local/include
Warning: /usr/local/share isn't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew.
If a brew tries to write a file to this directory, the install will
fail during the link step.
You should probably `chown` /usr/local/share
Warning: Some directories in /usr/local/share/locale aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:
/usr/local/share/locale
/usr/local/share/locale/be
/usr/local/share/locale/be/LC_MESSAGES
/usr/local/share/locale/ca
/usr/local/share/locale/ca/LC_MESSAGES
/usr/local/share/locale/da
/usr/local/share/locale/da/LC_MESSAGES
/usr/local/share/locale/de
/usr/local/share/locale/de/LC_MESSAGES
/usr/local/share/locale/el
/usr/local/share/locale/el/LC_MESSAGES
/usr/local/share/locale/es
/usr/local/share/locale/es/LC_MESSAGES
/usr/local/share/locale/fr
/usr/local/share/locale/fr/LC_MESSAGES
/usr/local/share/locale/ja
/usr/local/share/locale/ja/LC_MESSAGES
/usr/local/share/locale/nl
/usr/local/share/locale/nl/LC_MESSAGES
/usr/local/share/locale/sv
/usr/local/share/locale/sv/LC_MESSAGES
/usr/local/share/locale/tr
/usr/local/share/locale/tr/LC_MESSAGES
Warning: Some directories in /usr/local/share/man aren't writable.
This can happen if you "sudo make install" software that isn't managed
by Homebrew. If a brew tries to add locale information to one of these
directories, then the install will fail during the link step.
You should probably `chown` them:
/usr/local/share/man/de
/usr/local/share/man/de/man1
Warning: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. Some versions of the
"InstantOn" component of Airfoil are known to do this.
You should probably change the ownership and permissions of /usr/local
back to your user account.
Warning: Setting DYLD_LIBRARY_PATH can break dynamic linking.
You should probably unset it.
Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.
Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
/Library/Frameworks/Python.framework/Versions/2.7/bin/python-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config
/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config
/soft/star-hikianalia/bin/gsl-config
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.

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:
fftw
Warning: You have uncommitted modifications to Homebrew
If this a surprise to you, then you should stash these modifications.
Stashing returns Homebrew to a pristine state but can be undone
should you later need to do so for some reason.
cd /usr/local/Library && git stash && git clean -f
Warning: Some installed formula are missing dependencies.
You should `brew install` the missing dependencies:
brew install gmp harfbuzz icu4c libmpc mpfr
Run `brew missing` for more details.
先谢谢您的帮助！
它在错误消息中说明问题是什么；
Warning: /usr/local/include isn't writable
You should probably change the ownership and permissions of /usr/local
返回您的用户帐户。
如果你跑ls -l /usr/local/你应该有这样的输出：
total 4
-rw-r--r-- 1 user admin 493 23 Apr 15:14 CONTRIBUTING.md
drwxr-xr-x 17 user admin 578 5 May 14:54 Cellar
drwxr-xr-x 3 user admin 102 23 Apr 16:33 Frameworks
drwxr-xr-x 10 user admin 340 24 Apr 08:50 Library
Where user是您的用户名并且admin是你的组。如果您看到类似以下内容：
drwxr-xr-x 17 root wheel 578 5 May 14:54 Cellar
你必须跑chown -R user:admin /usr/local这会将所有权更改回您的用户。
这应该解决第一部分。但是，请注意，如果您之前运行过，这可能会阻止其他软件运行"sudo make install" software that isn't managed
by Homebrew.
