問題

在安裝Homebrew這一步報錯

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

這是因為本機沒有安裝xcode開發套裝。而Xcode Command Line Tools 是套裝的一部分。
既然不做蘋果應用程序開發，我們不需要安裝完整的xcode，
只需要下載Xcode Command Line Tools即可。
參考：

通過$ xcode-select --install下載會非常慢，所以直接訪問 https://developer.apple.com/downloads/more 下載dmg文件

下載

提高brew速度
