title: Application generating "Error: listen EACCES" while starting application with pm2 on port 80?
body: <p>We are using pm2 for starting my nodejs app on port 80 on ubuntu. But the application generating error <code>**Error: listen EACCES**</code>. Our pm2 version is 0.12.7 and we are using the following command:</p>
  
  <pre><code>sudo pm2 start app.js -- dev
  </code></pre>
  
  <p>On running <code>whereis node</code> we get the following result:</p>
  
  <pre><code>node: /usr/bin/node /usr/sbin/node
  </code></pre>
  
  <p>We have already tried following commands:</p>
  
  <pre><code>sudo apt-get install libcap2-bin
  sudo setcap cap_net_bind_service=+ep /usr/local/sbin/node
  </code></pre>
  
  <p>Any idea where are we going wrong?</p>
