An error occurred while installing json (2.6.3), and Bundler cannot continue.
看这个报错信息：
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
这告诉您缺少 Xcode 命令行工具。运行以下命令来安装它们：
xcode-select --install
按照屏幕上的提示，然后重试您的操作。
