xcrun: error: active developer path ("/Volumes/Xcode/Xcode-beta.app/Contents/Developer") does not exist, use `xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools (or see `man xcode-select`)
解决方案
在终端中修改你的CommandLine Tools的位置： xcode-select -switch /Applications/Xcode.app/Contents/Developer
