title: Error when giving the command Grunt
body: <p>I started to explore Grunt. Read several sites, I saw examples. Well, I created package.json and Gruntfile.js:</p>
  
  <p>package.json <a href="http://pastebin.com/Kkt8fuXJ" rel="nofollow">http://pastebin.com/Kkt8fuXJ</a></p>
  
  <p>Gruntfile.j <a href="http://pastebin.com/LnSmTzXZ" rel="nofollow">http://pastebin.com/LnSmTzXZ</a></p>
  
  <p>The organization of the folders of my project is:</p>
  
  <pre><code>root (index.html)
  -src (where is package.json and Gruntfile.js)
  -lib
   --css
    ---min
   --js
   --img
  </code></pre>
  
  <p>When I give the command grunt always happens this error:</p>
  
  <pre><code>Loading "Gruntfile.js" tasks...ERROR
  &gt;&gt; Error: Unable to parse "package.json" file (Unexpected token }).
  Warning: Task "default" not found. Use --force to continue.
  
  Aborted due to warnings.
  </code></pre>
  
  <p>If i remove pkg: grunt.file.readJSON('package.json'),:</p>
  
  <pre><code>        grunt.loadNpmTasks('grunt-contrib-imagemin');
          ^^^^^
  Loading "Gruntfile.js" tasks...ERROR
  &gt;&gt; SyntaxError: Unexpected identifier
  Warning: Task "default" not found. Use --force to continue.
  
  Aborted due to warnings.
  </code></pre>
  
  <p>What is wrong?</p>
  
  <p>Thanks</p>
