npm install won't install devDependencies
<p>On windows for some reason when I run <code>npm install</code> it won't install <strong>devDependencies</strong>. AFAIK it should. If I run <code>npm install --dev</code> <strong>devDependencies</strong> are installed. I don't understand why <code>npm install</code> doesn't install <strong>devDependencies</strong> too, but installs only dependencies. What could be the reason? How can I fix it?</p>

<p>Maybe something is wrong with my <em>package.json</em>? It is listed below if it may be helpful:</p>

<pre><code>{
  "name": "try-brunch",
  "version": "0.1.0",
  "private": "true",
  "devDependencies": {
    "brunch": "^2.0.4",
    "cssnano-brunch": "^1.1.5",
    "javascript-brunch": "^1.8.0",

    "uglify-js-brunch": "^1.7.8"
  },
  "dependencies": {
    "jquery": "^2.1.4"
  }
}
</code></pre>
