Welcome! Technically you don't *need* to install MacPorts if all you want is Cairo. You could build it and it's dependencies from source. But using MacPorts is indeed an easy way to get the job done. > I tried to install Macports on my Mac OS Sierra 10.12.6, and type "sudo > port install cairo", but it did not respond.

MacPorts is the command line program /opt/local/bin/port. The installer should have set up your PATH so that you can run it by just typing "port" instead of that full path. From your output above, I see you inadvertently entered MacPorts shell mode, indicated by the ">" prompt, by running "port" with no arguments. As it says, to exit that mode, type "quit" to get back to your normal shell's "$" prompt. At your normal shell "$" prompt, you can run "sudo port install cairo".
