title: Error: listen EACCES 0.0.0.0:80 OSx Node.js
body: <p>I'm following a tutorial in a angularJS book and have to setup a server. This is the server.js file: </p>
  
  <pre><code> var express = require('express');
    var app = express();
     app.use('/', express.static('./'));
      app.listen(80);
  </code></pre>
  
  <p>I get this error: </p>
  
  <pre><code>$ node server.js
  events.js:154
        throw er; // Unhandled 'error' event
        ^
  
  Error: listen EACCES 0.0.0.0:80
  </code></pre>
  
  <p>I know already, that the Error EACCES means that i don't have access rights to the port 80, but i don't know how to fix this.
  Any help much appreciated! </p>
