偶然会因为网络问题可以先设置代理再执行上面这段安装代码。代理设置方式如底下描述，对安装脚本也是适用的。
查看安装之后的版本：
% brew --version
Homebrew 3.1.5
Homebrew/homebrew-core (git revision 5e014bf244; last commit 2021-05-02)
代理设置
可以通过 export ALL_PROXY=proxyIP:port 方式设置代理（指向http代理）：
$ export ALL_PROXY=127.0.0.1:1087
$ brew install socat
Updating Homebrew...
==> Installing dependencies for socat: openssl@1.1 and readline
==> Installing socat dependency: openssl@1.1
==> Downloading https://homebrew.bintray.com/bottles/openssl@1.1-1.1.1d.catalina
==> Downloading from https://akamai.bintray.com/d7/d7f992ebfd78f80828051f6dc6a1a
######################################################################## 100.0%
==> Pouring openssl@1.1-1.1.1d.catalina.bottle.tar.gz
也可以使用 socks5 代理，地址需要指定为 socks5 格式：
$ export ALL_PROXY=socks5://127.0.0.1:11080
$ brew install wget
Updating Homebrew...
==> Installing dependencies for wget: gettext, libunistring and libidn2
==> Installing wget dependency: gettext
==> Downloading https://homebrew.bintray.com/bottles/gettext-0.20.1.catalina.bot
==> Downloading from https://akamai.bintray.com/10/107d7f386fbeea6979f9376cdbbcf
######################################################################## 100.0%
==> Pouring gettext-0.20.1.catalina.bottle.tar.gz
代理快捷设置
修改 ~/.zshrc 文件，加入以下内容：
alias proxyon='export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890'
alias proxyoff='unset https_proxy http_proxy all_proxy'
这样就可以方便的在需要时设置brew的代理了。
