title: node.js express-coffee Error: ENOENT, no such file or directory
body: <p>I installed the latest <a href="https://github.com/twilson63/express-coffee" rel="nofollow">express-coffee</a> and installed <a href="https://github.com/lorenwest/node-config" rel="nofollow">node-config</a> too. I created a simple src/config/default.yaml</p>
  
  <pre><code>Database:
      db_host: localhost
      db_name: test
  </code></pre>
  
  <p>In my src/models/index.coffee</p>
  
  <pre><code>config = require('config').Database
  
  console.log "host: #{config.db_host}"
  </code></pre>
  
  <p>But when trying to start the server with <code>cake dev</code> or even <code>cake build &amp;&amp; node app</code> I am getting the following error:</p>
  
  <pre><code>Cannot write runtime.json file Error: ENOENT, no such file or directory
  </code></pre>
  
  <p>Tried searching for the issue here and on Google but wasn't able to find anything. Even the few hits on just ENOENT or node-config runtime.json haven't been helpful. Anyone else run into this problem before ? </p>
