$ git -C "$(brew --repo)" remote set-url origin https://mirrors.aliyun.com/homebrew/brew.git
# 修改 homebrew-core.git 为阿里源
$ git -C "$(brew --repo homebrew/core)" remote set-url origin https://mirrors.aliyun.com/homebrew/homebrew-core.git
# 修改 xxxx的源，后面的xxxxxxxxxxxxxxxxx参考上面设置，也就是其仓库地址，这里可以使用https://codechina.csdn.net/mirrors克隆github仓库，然后替换地址
$ git -C "$(brew --repo xxxxx)" remote set-url origin xxxxxxxxxxxxxxxxxxxxxx
# 例子:facebook的homebrew-fb
git -C "$(brew --repo facebook/fb)" remote set-url origin https://gitclone.com/github.com/facebook/homebrew-fb.git
brew 使用的是curl，所以查看curl的代理即可，如何查看呢？可以在curl http://google.com -v看一下输出
命令行形式。形如curl http://google.com -x http://127.0.0.1:7890或者curl http://google.com -x socks4://127.0.0.1:1089
curl的代理配置文件在~/.curlrc文件里，格式如下
http
proxy = "127.0.0.1:7890"
或者
socks5
socks5 = "127.0.0.1:1089"
但socks5未测试成功，即使以命令行-x 选项也不行，可能是代理的问题
但是该方式测试失败，测试环境如下：
--disabale选项，该选项禁止了.curlrc文件方式export ALL_PROXY=socks5://127.0.0.1:1089
brew在安装某些软件时会涉及到/usr/local/目录的读写权限，会出现类似如下错误
Error: /usr/local/Cellar/buck/2021.01.12.01 is not a directory
这时执行
sudo chown -R $(whoami) /usr/local/Cellar/
即可，但又会出现另一个问题
Error: Failure while executing; `cp -pR /private/tmp/d20210826-15074-zh9zmn/buck/. /usr/local/Cellar/buck` exited with 1. Here's the output:
cp: /usr/local/Cellar/buck/./2021.01.12.01_1/bin/buck: Permission denied
brew install libusb
# 查看安装路径
brew info libusb
# 将路径添加到系统查找目录
export DYLD_LIBRARY_PATH="/usr/local/Cellar/libusb/1.0.27/lib:$DYLD_LIBRARY_PATH"
brew install blacktop/tap/ipsw
