HEAD is now at 3eb50a0 tools: Flip order of windows.h and winsock2.h to get rid of compiler warning (Windows) Error: Xcode alone is not sufficient on Catalina. Install the Command Line Tools: xcode-select --install
去试试：
xcode-select --install
xcode-select 命令需要使用命令行开发者工具，您要现在安装该工具吗？ 选取安装来立刻下载并安装命令行开发者工具。
和：
“Install Command Line Developer Tools.app”需要下载字体“华文黑体”。
电脑尚未连接电源。 为获得最佳效果，请在安装前先将电脑接通电源。
再去试试：
xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates
已安装。看起来没问题了。
重新试试：
brew install --HEAD usbmuxd
就可以正常安装了。
【总结】
此处
brew install --HEAD usbmuxd
报错：
Error: Xcode alone is not sufficient on Catalina. Install the Command Line Tools: xcode-select --install
根据提示去：
xcode-select --install
一路安装，即可。
