title: "npm install [package]" doesn't update package.json
body: <p>I've been using Laravel and trying to use <code>angular-ui-sortable</code> and <code>angular-utils-pagination</code>.</p>
  
  <p>I installed them with <code>npm</code>, but can't get <code>package.json</code> updated for <code>angular-utils-pagination</code>.</p>
  
  <p>The file now looks like...</p>
  
  <pre><code> {
    "private": true,
    "devDependencies": {
     "gulp": "^3.8.8"
    },
    "dependencies": {
      "angular-ui-sortable": "^0.14.0",
      "bootstrap-sass": "^3.0.0",
      "laravel-elixir": "^4.0.0"
    }
  }
  </code></pre>
  
  <p>The point is that <code>angular-ui-sortable</code> is there but <code>angular-utils-pagination</code> is not. Both files are under <code>node_module</code> folder. As far as I understand, those libraries have to be under <code>dependencies</code> in <code>package.json</code> for them to be available.</p>
  
  <p>Any advice will be appreciated.</p>
