body: <p>I am using W7 64bit. Simply put, when I enter:</p>

  <p>I get this result:</p>

  <p>Uninstalling and reinstalling does not work.</p>
  
  <p>I'm trying to install libv8 because it's a dependency for twitter-bootstrap-rails.</p>
  
  <p>EDIT: As I said, I'm on Windows, and I'm realizing now that there's a filepath listed in this error as /usr/bin/env. So that's weird.</p>
