Can anyone tell me why? I’ve installed the full Xcode and agreed to the new licence agreement of Xcode. Thanks
Btw, I can run .help .license with no errors

Hi,

Did you install the xcode command line tools? xcode-select --install should help.

Thanks Axel. I basically reinstalled everything related to Xcode and now the error has gone. Thanks
