安装 Homebrew 执行完安装语句
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
抛出如下异常
fatal: unable to access 'https://github.com/Homebrew/homebrew-core/': LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54
Error: Failure while executing; `git clone https://github.com/Homebrew/homebrew-core /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1` exited with 128.
Error: Failure while executing; `/usr/local/bin/brew tap homebrew/core` exited with 1.
Failed during: /usr/local/bin/brew update --force
解决办法
首先，更换有效的镜像地址；
git clone git://mirrors.ustc.edu.cn/homebrew-core.git/ /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1
如果提示已经存在直接到下一步
其次，前往至 homebrew-core 将其当前的镜像地址也更为有效的地址；
cd "$(brew --repo)"
git remote set-url origin https://mirrors.ustc.edu.cn/brew.git
cd "$(brew --repo)/Library/Taps/homebrew/homebrew-core"
git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git
再其次，将如上配置文件内容更替后，重新执行更新；
brew update
最后，执行完如上操作后，终端显示如下字样内容即可。
Already up-to-date.
