Что случилось с Gulp ?

Всем привет!
Помогите разобраться в появившейся ошибке в Gulp.js

Gulpfile.js

var gulp = require('gulp'),
concatCss = require('gulp-concat-css'),
    minifyCSS = require('gulp-minify-css'),
    prefix = require('gulp-autoprefixer'),
    rename = require('gulp-rename'),
    uglify = require('gulp-uglify'),
    concat = require('gulp-concat'),
    imagemin = require('gulp-imagemin');

// css
gulp.task('css', function () {
  gulp.src('css/*.css')
    .pipe(concatCss('bundle.css'))
    .pipe(prefix('last 2 version', 'safari 5', 'ie 8', 'ie 9', 'opera 12.1', 'ios 6', 'android 4'))
    .pipe(minifyCSS({noRebase:true}))
    .pipe(rename('bundle.min.css'))
    .pipe(gulp.dest('app/css'));
});

gulp.task('scripts', function() {
return gulp.src('js/*.js')
.pipe(concat('main.js'))
.pipe(gulp.dest('app/js'))
.pipe(rename({ suffix: '.min' }))
.pipe(uglify())
.pipe(gulp.dest('app/js'));
});

  // Compress Task
  gulp.task('compress', function() {
    gulp.src('img/*')
    .pipe(imagemin({
      progressive: true
    }))
    .pipe(gulp.dest('app/img'));
  });

gulp.task('default', ['css', 'scripts', 'compress']);
