title: grunt not installing/available globally
body: <p>I'm trying to install grunt globally using the following command from the command line:</p>
  
  <p>npm install -g grunt</p>
  
  <p>The installation command seems to succeed with no errors written to the console.  However, when I enter grunt at the command line after install I get the following error:</p>
  
  <p>'grunt' is not recognized as an internal or external command, operable program or batch file</p>
  
  <p>It looks like the install command installs grunt into the following directory by default:</p>
  
  <p>c:\users\my_login_id\appdata\roaming\npm\node_modules\grunt</p>
  
  <p>Not sure if the user-specific install directory might have anything to do with the issue?  Any idea what might be causing the problem or how to debug?</p>
