title: Having trouble installing libxml-ruby on windows
body: <p>First of all thank you for your time.</p>
  
  <p>I've been having some trouble installing libxml-ruby on my windows 8 OS. I have ruby installed and want to use libxml specifically to modify xmls because other members of my team have already started with libxml. The problem is that they were using linux and I'm on windows. I could try to put everything on a vm but I don't think I should need to. </p>
  
  <p>They had issues installing on linux too but their solution and problem was different from mine.</p>

  <p>I have tried installing zlib (binaries) and pointing to the zlib binary.
  That didn't really help.</p>
  
  <p>So now I'm googling :)</p>
