npm run does nothing : <p>I've been working with Node.js/npm for a while, but I never used npm scripts. I was quite surprised to find that I can't get them to work at all on my Windows/Cygwin system. With a package.json like this ...</p>

<pre><code>{
  "name": "demo",
  "scripts": {
    "env": "env",
    "hello": "echo Hello!",
    "crap": "I am complete nonsense."
  }
}
</code></pre>

<p>... all three npm run commands do nothing. <code>npm run crap</code> executes and returns immediately with an OK status (I tested with the -dd parameter); <code>npm run doesntexist</code> throws the expected error. Testing without Cygwin on the regular Windows shell made no difference.</p>
