我不懂ruby，这应该是新版本的berw下载回来无法安装？
求大神来个来解决办法，某度上根本搜索不到相关的，google后发现有，但貌似没给出解决办法，或许我英文太烂没看懂。

网上看了一下用brew doctor看下问题，一执行结果出来一大堆问题

huangwhMac:~ huangwh$ 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 or file an issue; just ignore this. Thanks!

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/libluajit-5.1.2.0.2.dylib

Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected .pc files:
  /usr/local/lib/pkgconfig/luajit.pc

Warning: Unbrewed static libraries 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 static libraries:
  /usr/local/lib/libluajit-5.1.a

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:
  autoconf
  cloog
  freetype
  gcc
  gmp
  gmp@4
  intltool
  isl
  isl@0.11
  libevent
  libmpc
  libmpc@0.8
  libtool
  mcrypt
  memcached
  mhash
  mpfr
  mpfr@2
  neon
  pcre
  pkg-config
  re2c
  scons
  subversion17
  unixodbc
  wget

Warning: An outdated version (2.8.2) of Git was detected in your PATH.
Git 2.14.3 or newer is required for Homebrew.
Please upgrade:
  brew upgrade git

Warning: /usr/bin occurs before /usr/local/bin
This means that system-provided programs will be used instead of those
provided by Homebrew. The following tools exist at both paths:
  easy_install
  easy_install-2.7
  git
  git-cvsserver
  git-receive-pack
  git-shell
  git-upload-archive
  git-upload-pack
  phar
  phar.phar
  php
  php-config
  phpize
  svn
  svnadmin
  svndumpfilter
  svnlook
  svnserve
  svnsync
  svnversion

Consider setting your PATH so that /usr/local/bin
occurs before /usr/bin. Here is a one-liner:
  echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bash_profile

Warning: Homebrew's sbin was not found in your PATH but you have installed
formulae that put executables in /usr/local/sbin.
Consider setting the PATH for example like so
  echo 'export PATH="/usr/local/sbin:$PATH"' >> ~/.bash_profile

Warning: Your Xcode (7.3) is outdated.
Please update to Xcode 8.2.1 (or delete it).
Xcode can be updated from the App Store.
