title: Node sass not importing
body: <p>I am building a sass compiler with nodejs, electron, and node-sass.</p>
  
  <p>There will be a config file that will describe some "sass compilers" for many projects and the user will have the ability to activate and deactivate them through a GUI.</p>
  
  <p>I managed with "electron" to create the interface and with the use of electron`s "ipcmain" to initiate the compilers on demand.</p>
  
  <p>To init a compiler, I spawn a child process which encloses the whole compiler.</p>
  
  <p>The compilation is done with following code:</p>
  
  <pre><code>var result = this.sass.renderSync({
          file: 'C:\\Users\\George\\Desktop\\css_compiler_tests\\test3\\scss\\style.scss',
          outFile: 'C:\\Users\\George\\Desktop\\css_compiler_tests\\test3\\css\\style.css',
          includePaths:[
              'C:\\Users\\George\\Desktop\\css_compiler_tests\\test3\\scss\\',
              'C:\\Users\\George\\Desktop\\css_compiler_tests\\test3\\scss\\foundation\\components\\'
          ]
      });
  </code></pre>
  
  <p>I execute the compilation using absolute paths but the files us relative paths.</p>
  
  <p>I run my program/gui and activated the compiler and I got a CSS file. <br>
  The problem is that some imports are missing.</p>
  
  <p>My root folder is at 'C:\Users\George\Desktop\css_compiler_tests\test3\'.<br>
  I try to compile 'scss\style.scss' which imports 'scss_inculded-files.scss'.</p>
  
  <p>The file 'scss_inculded-files' imports 'scss\foundation.scss' which imports form 'scss\foundation\components'.</p>
  
  <p>Here is an example:</p>
  
  <pre><code>/*scss\style.scss*/
  @import "included-files";
  
  /*scss\_inculded-files.scss*/
  @import 
  "includes/fonts",
  "includes/custom-colors",
  "includes/foundation-custom-settings",
  "foundation/settings",
  "foundation";
  
  /*scss\foundation.scss*/
  @import
  "foundation/components/grid",
  "foundation/components/accordion";
  </code></pre>
  
  <p>The content of the two last imports is missing.</p>
  
  <p>Finaly I tried from command line and got the same error:</p>
  
  <pre><code> D:\mytests\nodejs\nodeSass&gt; node_modules/.bin/node-sass C:\Users\George\Desktop\css_compiler_tests\test3\scss\style.scss -o C:\Users\George\Desktop\css_compiler_tests\test3\scss\ --include-path C:\Users\George\Desktop\css_compiler_tests\test3\scss\
  </code></pre>
  
  <p>Is there a way to include those missing files?</p>
  
  <p>Thank you in advance.</p>
  
  <p><b>Edit 1</b>
  After some experimentation I found out that the Mixins are the problem.</p>
  
  <p>Let say I have a Mixin like that:</p>
  
  <pre><code>@mixin headline($size, $color: $base-color) {
      color: $color;
      font-size: $size;
  }
  </code></pre>
  
  <p>It is compiled perfectly if I call it like that:</p>
  
  <pre><code>h1 {
      @include headline($color: blue, $size: 12px);
  }
  </code></pre>
  
  <p>If I don't call it isn't compiled.</p>
  
  <p>I am using Foundation Zurb framework which I believe auto includes the mixins.</p>
