title: Gulp was working but then stopped
body: <p>I am stuck, I have been trying to learn gulp and I am slowly putting together a gulpfile.</p>
  
  <p>I got to a point testing as I went along and everything was fine. A few days later I returned to continue with it and now it doesn't work. I have no clue whats wrong.</p>
  
  <p>my gulp file</p>
  
  <pre><code>var gulp = require('gulp'),
  
  // required for CSS and LESS
  less = require('gulp-less');
  prefix = require('gulp-autoprefixer'),
  minifyCSS = require('gulp-minify-css');
  
  // required for JS
  concat = require('gulp-concat'),
  uglify = require('gulp-uglify'),
  
  rename = require("gulp-rename");
  
  var paths = {
    src : {
      less       : '.assets/less/styles.less',
      js_main    : '.assets/scripts/main.js',
      js_plugins : '.assets/scripts/plugins/*.js',
      img        : ''
    },
    dest : {
      css : './public/assets/css/',
      js  : './public/assets/js/',
      img : ''
    }
  };
  
  gulp.task('styles', function() {
    gulp.src( paths.src.less )
    .pipe( less() )
    .pipe( prefix("last 2 version", "&gt; 1%", "ie 8", "ie 7") )
    .pipe( gulp.dest( paths.dest.css ) )
    .pipe( rename('styles.min.js') )
    .pipe( minifyCSS() )
    .pipe( gulp.dest( paths.dest.css ) );
   });
  
  gulp.task('scripts', function() {
    gulp.src( paths.src.js_main )
    .pipe( concat('main.js') )
    .pipe( gulp.dest( paths.dest.js ) )
    .pipe( rename('main.min.js') )
    .pipe( uglify() )
    .pipe( gulp.dest( paths.dest.js ) );
  });
  
  gulp.task('plugins', function() {
    gulp.src( paths.src.js_plugins )
    .pipe( concat('plugins.js') )
    .pipe( gulp.dest( paths.dest.js ) )
    .pipe( rename('plugins.min.js') )
    .pipe( uglify() )
    .pipe( gulp.dest( paths.dest.js ) );
  });
  </code></pre>
  
  <p>So this was working when I stopped working on it but when I ran gulp styles in terminal days later i get this:</p>
  
  <pre><code>$ gulp styles
  [gulp] Using gulpfile ~/projects/boilerplates/website-boilerplate/gulpfile.js
  [gulp] Starting 'styles'...
  [gulp] Finished 'styles' after 3.8 ms
  </code></pre>
  
  <p>so far I have tried to delete the installed node modules and re install them. I have also tried installing gulp globally again.</p>
  
  <p>Would appreciate any help or suggestions. </p>
