mac上安装包管理工具homebrew失败！【Failure while executing； `git clone https://github.com/Homebrew/homebrew-cor】

1.错误代码 

Cloning into '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core'...
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` exited with 128.
Error: Failure while executing; `/usr/local/bin/brew tap homebrew/core` exited with 1.

换了新mac, homebrew死活装不上，老是卡在这里，试了网上的各种方法都没能成功！

最后在官网的社区里找到了答案！答案

2.具体操作方法，在命令行里执行：

git clone https://github.com/Homebrew/homebrew-core /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core --depth=1

3.装完后诊断一下：

$ brew doctor
# Your system is ready to brew.

搞定！！！
