title: 'node' is not recognized as an internal or external command... during an npm install
body: <p>Totally new to node.js/npm, trying to get a couple new front-end tools under my belt. I'm on a windows box. I can do:</p>
  
  <pre><code>D:\Users\saturdayplace\Documents\www\accntr&gt;node -v
  v4.1.2
  
  D:\Users\saturdayplace\Documents\www\accntr&gt;which node
  C:\Program Files\nodejs\node.EXE
  
  D:\Users\saturdayplace\Documents\www\accntr&gt;echo %path%
  &lt; a bunch of stuff that includes C:\Program Files\nodejs\ &gt;
  </code></pre>
  
  <p>And there's a node.exe in that folder. So, I'm fairly certain that my case is different from the typical, "Is it on your path?" or "Is node actually installed?" situations. I've <code>npm install</code>d a bunch of other things (including stuff that needs a C (or whatever) compiler), but for some reason, sass-gulp just don't wanna play nice.  Here's what it does:</p>
  
  <pre><code>D:\Users\saturdayplace\Documents\www\accntr&gt;npm install gulp-sass --save-dev
  npm WARN install Couldn't install optional dependency: Unsupported
  npm WARN prefer global node-gyp@3.0.3 should be installed with -g
  
  &gt; node-sass@3.3.3 install D:\Users\saturdayplace\Documents\www\accntr\node_modules\node-sass
  &gt; node scripts/install.js
  
  'node' is not recognized as an internal or external command, operable program or batch file.
