解决方案
阅读报错信息，尝试各种方案，终于解决！
首先在终端输入下面命令下载

xcode-select --install 
1.如果报错如下
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
2.表示已经存在，重置即可
xcode-select --reset

如果下载 xcode-select失败，那就需要到官方给开发者提供的下载处直接去下载命令行工具（Command Line Tools）

1.地址：https://developer.apple.com/download/all/
2.在搜索框，搜索：Command Line Tools
3. 选择合适的版本下载即可

4.安装简单，傻瓜式安装即可，安装完成后，再执行上述两个命令即可

xcode-select --install 
1.如果报错如下
xcode-select: error: command line tools are already installed, use "Software Update" to install updates
2.表示已经存在，重置即可
xcode-select --reset
