Gulp Error

Recently I started using gulp.js for my web-app. The web app is running on ruby on rails. Here is my code:

```var gulp = require('gulp'), coffee = require('gulp-coffee'), concat = require('gulp-concat'), uglify = require('gulp-uglify'), clean = require('gulp-clean'), sass = require('gulp-sass'), imagemin = require('gulp-imagemin');

var paths = { scripts: ['../javascripts//*.coffee', '../app/assets/scripts//.js'], styles: ['../stylesheets//.scss', '../app/assets/stylesheets//*.css'], images: ['../images//*'] };

gulp.task('scripts', function() { // Compile Coffescript, minify and uglify JS return gulp.src(paths.scripts) .pipe(coffee()) .pipe(uglify()) .pipe(concat('all.min.js')) .pipe(gulp.dest('../javascripts')); });

gulp.task('styles', function () { return gulp.src(paths.styles) .pipe(sass({style: 'compressed'})) .pipe(concat('main.css')) .pipe(gulp.dest('../stylesheets')); });

// Copy all static images gulp.task('images', function() { return gulp.src(paths.images) .pipe(imagemin({optimizationLevel: 5})) .pipe(gulp.dest('../images')); });

// Clean up the dist folder gulp.task('clean', function () { return gulp.src(['../stylesheets/', '../javascripts/', '../images/'], { read: false }).pipe(clean()); });

// Rerun the task when a file changes gulp.task('watch', function() { gulp.watch(paths.scripts, ['scripts']); gulp.watch(paths.styles, ['styles']); gulp.watch(paths.images, ['images']); });

gulp.task('build', ['scripts', 'styles', 'images']);

// The default task (called when you run gulp from cli) gulp.task('default', ['clean'], function() { gulp.start('build'); });

Here is my error:

stream.js:94 
      throw er; // Unhandled stream error in pipe.
            ^
Error: source string:27: error: invalid top-level expression
