  npm not ok
  It worked
  </code></pre>
  
  <p>What should I do? I tried these with no success:</p>
  
  <pre><code>chown -R cirk /usr/lib/nodejs
  // and also this
  chown -R cirk /usr/lib/node_modules (node_modules is empty it tries to install NPM here or what)
  </code></pre>
  
  <p>actually it did something, as you can see it writes at the end <code>It worked</code> what is a big lie!</p>
