title: Gulp/Browserify Error
body: <p>I'm new to node and trying to setup browserify with gulp as per this tutorial: <a href="https://www.learnhowtoprogram.com/javascript/introduction-to-javascript/using-browserify-with-gulp" rel="nofollow">https://www.learnhowtoprogram.com/javascript/introduction-to-javascript/using-browserify-with-gulp</a>. Please help I've tried googling, no solution.</p>
  
  <p>My gulp file shows:</p>
  
  <pre><code>var gulp  = require('gulp');
  var browserify = require('browserify');
  var source = require('vinyl-source-stream');
  gulp.task('jsBrowserify', function() {
    return browserify({ entries: ['./js/pingpong-interface.js'] })
      .bundle()
      .pipe(source('app.js'))
      .pipe(gulp.dest('./build/js'));
  });
  </code></pre>
  
  <p>I ran in terminal:</p>
  
  <pre><code>gulp jsBrowserify
  </code></pre>
  
  <p>this should create the 'build' folder.</p>
  
  <p>Instead I get the error:</p>
  
  <pre><code>C:\Users\danrusu\Documents\Coding Docs\projects\pingpong&gt;gulp jsBrowserify
  (node:7728) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
