    var spriteData = gulp.src('./src/images/sprite/*.png')
        .pipe(spritesmith('sprites.png', {
            imgName: 'sprite.png',
            cssName: 'sprite.styl'
        }));

    var imgStream = spriteData.img.pipe(buffer()).pipe(gulp.dest('./src/styles/utils'));
    var cssStream = spriteData.css.pipe(gulp.dest('./src/images'));

    return merge(imgStream, cssStream);
});

There seems to be a string being passed as the first parameter. The first parameter should be an object. The following should work:

gulp.task('sprite', function(){
    var spriteData = gulp.src('./src/images/sprite/*.png')
        .pipe(spritesmith({
            imgName: 'sprite.png',
            cssName: 'sprite.styl'
        }));

    var imgStream = spriteData.img.pipe(buffer()).pipe(gulp.dest('./src/styles/utils'));
    var cssStream = spriteData.css.pipe(gulp.dest('./src/images'));

    return merge(imgStream, cssStream);
});
