macOS Catalina
10.15.2 (19C57)

Xcode 11.3

xcode version

While Pallet probably still fails to build for other reasons (see existing tickets), this message indicates that running xcodebuild -version didn't work.

This worked for me.

From CatalinaProblems

MacPorts must be re-installed in a version configured for macOS 10.15 Catalina.

Ensure you have Xcode 11.1 or greater installed and selected (e.g. sudo xcode-select -s /Applications/Xcode.app/Contents/Developer), and that you have the command line tools installed (xcode-select --install). You also have to agree to the license by running sudo xcodebuild -license.

There have been reports that the -license option might not be sufficient alone, and following command might be required to agree to the license: sudo xcodebuild -runFirstLaunch

The command xcode-select -s /Applications/Xcode.app/Contents/Developer helps, for my issue on macOS Big Sur(11.0.1):

$ sudo port install nodejs15

$ xcodebuild -version
xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

There doesn't seem to be anything here to do with Pallet -- this looks like the user needed to install and possibly select xcode. Please reopen if otherwise.
