title: Rails: Why "sudo" command is not recognized?
body: <p>In my application directory (on Windows) I run:</p>
  
  <pre><code>sudo pdfkit --install-wkhtmltopdf
  </code></pre>
  
  <p>as explained <a href="http://blog.10to1.be/rails/2010/08/18/pdfkit-and-ruby-on-rails/" rel="noreferrer">here</a>, but I got this error:</p>
  
  <blockquote>
    <p>'sudo' is not recognized as an internal or external command, 
        operable program or batch file.</p>
  </blockquote>
  
  <p>What could be the problem ?</p>
