title: Python - Node.js (V8) runtime is not available on this system
body: <p>I'm getting the following error when trying to use ExecJS:</p>
  
  <pre><code>execjs.RuntimeUnavailable: Node.js (V8) runtime is not available on this system
  </code></pre>
  
  <p>I have node.js installed on my machine (Ubuntu 14.04). <code>Which Node</code> outputs <code>/usr/bin/node</code></p>
  
  <p>Any ideas?</p>
