NCP create a dotfile instead directory

ncp('package.config', './build/.ebextensions./.', function (err) {
        if (err) {
                return console.error(err);
        }
        console.log('API copied');
});

Whats is de reason because npc create a .ebextensions. FILE instead .ebextensions. FOLDER

I try ussing excec and simple mkdir .ebextensions. command and not working.
