在安装Homebrew这一步报错
Press RETURN to continue or any other key to abort
==> Installing the Command Line Tools (expect a GUI popup):
==> /usr/bin/sudo /usr/bin/xcode-select --install
Password:
xcode-select: note: install requested for command line developer tools
Press any key when the installation has completed.
==> /usr/bin/sudo /usr/bin/xcode-select --switch /Library/Developer/CommandLineTools
xcode-select: error: invalid developer directory '/Library/Developer/CommandLineTools'
Failed during: /usr/bin/sudo /usr/bin/xcode-select --switch /Library/Developer/CommandLineTools
这是因为本机没有安装xcode开发套装。而Xcode Command Line Tools 是套装的一部分。
既然不做苹果应用程序开发，我们不需要安装完整的xcode，
只需要下载Xcode Command Line Tools即可。

通过$ xcode-select --install下载会非常慢，所以直接访问 https://developer.apple.com/downloads/more 下载dmg文件
