gulp.task('default', function() {
    // Tarefas
});

gulp.task('compileStyles', function() {
    gulp.src('public/assets/css/style.scss')
        .pipe(sass({
            noCache      : true,

gulp.task('watch', function() {
    server.listen(35729, function( err ) {
        if ( err ) { return console.log( err ); }

        gulp.watch('public/assets/css/**/*.{sass,scss}', [
            'compileStyles'
        ]);
    });
});

The error message says the livereload server is failing to load because the address is already in use.

Are you running the projects at the same time? To do that, you need the two livereload servers to be on different ports. You can configure that by changing 35729 to 35728 in one of your gulp files.

Depending on how your browser is setup, you may need to adjust its settings. Give it a try though, it might be fine.
