 > 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
 Error: Port nodejs15 requires a full Xcode installation, which was not
 found on your system.
 Error: You can install Xcode from the Mac App Store or
 https://developer.apple.com/xcode/
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.
 Error: Processing of port nodejs15 failed
 }}}
 {{{
 $ xcodebuild -version
 xcode-select: error: tool 'xcodebuild' requires Xcode, but active
 developer directory '/Library/Developer/CommandLineTools' is a command
 line tools instance
 }}}
