Не работает плагин gulp-rigger, почему?

var gulp 		 = require('gulp'), 
	sass 		 = require('gulp-sass'), 
	rigger 		 = require('gulp-rigger'), 
	browserSync  = require('browser-sync'), 
	del          = require('del'); 
 
gulp.task('sass', function(){ 
	return gulp.src('app/sass/**/*.scss') 
	.pipe(sass()) 
	.pipe(gulp.dest('app/css')) 
	.pipe(browserSync.reload({stream:true})) 
}); 
 
gulp.task('browser-sync', function(){ 
	browserSync({ 
		server: { 
			baseDir: 'app' 
		}, 
		notify: false 
	}) 
}); 
 
gulp.task('html', function(){ 
    gulp.src('app/*.html') 
        .pipe(rigger()) 
        .pipe(gulp.dest('dist/')); 
}); 
 
 
gulp.task('clean', function() { 
	return del.sync('dist');  
}); 
 
gulp.task('watch', ['browser-sync', 'sass'], function(){ 
	gulp.watch('app/sass/**/*.scss', ['sass']); 
	gulp.watch('app/*.html', browserSync.reload); 
	gulp.watch('app/js/**/*.js', browserSync.reload); 
}); 
 
gulp.task('build', ['clean', 'sass'],  function(){ 
		var buildCss = gulp.src('app/css/**/*') 
		.pipe(gulp.dest('dist/css')); 
		 
		var buildFonts = gulp.src('app/fonts/**/*') 
		.pipe(gulp.dest('dist/fonts')) 
 
		var buildJs = gulp.src('app/js/**/*')  
		.pipe(gulp.dest('dist/js')) 
 
		var buildHtml = gulp.src('app/*.html') 
		.pipe(gulp.dest('dist')); 
})
