title: Error when installing gulp on windows 7 using msysGit
body: <p>I'm trying to install gulp using <a href="http://travismaynard.com/writing/getting-started-with-gulp" rel="nofollow">this tut</a> and I got the following error. I'm not really sure why, maybe something with my directory choice? I'm using <a href="https://msysgit.github.io/" rel="nofollow">msysGit</a>.</p>
