Thanks @giovanni
I put this into the Run-Script.
Would I have to download Xcode for this to work? It takes a huge amount of space on my disk. (sorry for the noob questions)
Debugger:

If developer tools are located at a non-default location on disk, use `sudo xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools, and cancel the installation dialog.
See `man xcode-select` for more details.
