几天前，我运行了brew update，试图在我的Mac上更新homebrew（我使用OSX 10.9.5）。当我运行这个命令时，我得到了以下回复：
dyld: Library not loaded: /usr/local/opt/pcre2/lib/libpcre2-8.0.dylib

You can use `brew link curl` to link this version.

Warning: git 2.20.1 is already installed and up-to-date
To reinstall 2.20.1, run `brew reinstall git`
Error: Git must be installed and in your PATH!
我也运行了brew doctor，以查看是否有任何更改。这是显示的内容。

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: "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:
/Users/Robby/anaconda2/bin/curl-config
/Users/Robby/anaconda2/bin/freetype-config
/Users/Robby/anaconda2/bin/icu-config
/Users/Robby/anaconda2/bin/krb5-config
/Users/Robby/anaconda2/bin/libpng-config
/Users/Robby/anaconda2/bin/libpng16-config
/Users/Robby/anaconda2/bin/ncursesw6-config
/Users/Robby/anaconda2/bin/pcre-config
/Users/Robby/anaconda2/bin/python-config
/Users/Robby/anaconda2/bin/python2-config
/Users/Robby/anaconda2/bin/python2.7-config
/Users/Robby/anaconda2/bin/xml2-config
/Users/Robby/anaconda2/bin/xslt-config
Warning: Git could not be found in your PATH.
Homebrew uses Git for several internal functions, and some formulae use Git
checkouts instead of stable tarballs. You may want to install Git:
brew install git
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
automake
bash-completion
brotli
c-ares
cask
cmake
cunit
docbook
docbook-xsl
doxygen
emacs
fontconfig
freetype
gdbm
geoip
gmp
gnutls
htop
itstool
jansson
jemalloc
jpeg
libev
libevent
libpng
libtasn1
libtool
libunistring
nettle
nmap
p11-kit
pcre2
pkg-config
python@2
watch
Warning: You are using macOS 10.9.
We (and Apple) do not provide support for this old version.
You may encounter build failures and other breakages.
Please create pull requests instead of asking for help on
Homebrew's GitHub, Discourse, Twitter or IRC. You are
responsible for resolving any issues you experience, as
you are running this old version.
Warning: Some installed formulae are missing dependencies.
You should `brew install` the missing dependencies:
brew install python
Run `brew missing` for more details.
当我运行brew missing时，出现了以下内容。

有什么想法吗？我被难住了。
git未在路径中，则可以通过将git添加到路径中来解决此问题。您是否安装了git？您是如何安装的？您能否在终端上运行git --version？ - Bagus Tesa
