title: Rails, permissions denied cache with Windows
body: <p>I have to migrate my local rails app from a Mac environment to Windows. When I try to start the server (rails s) and load localhost:3000, I get the following error:</p>
  
  <blockquote>
    <p>Permission denied @ sys_fail2 -

  <p>I understand it's a permission error and searched on the internet to solve it but couldn't find a solution. I'm not really familiar with Windows, any help appreciated. Thanks!</p>
