title: Gulp-sass fails to compile scss file
body: <p>I'm using Gulp to compile my sass into css. A simple task compiles the <code>style.scss</code> file in the <code>_/sass</code> directory and saves the output into the root of the project. <code>style.scss</code> is used merely to import other files in the <code>_/sass</code> directory.</p>
  
  <p>When I run the default task from the command line (<code>$ gulp</code>) I get an error that the sass can't compile. It is included below in full. I have removed all content from the included files and run the task again. I still receive the same error (something I read online suggested this might test for an encoding issue. I don't fully understand encoding and how that might break things in my scenario).</p>
  
  <p>I've also run from the command line <code>$ sass _/sass/style.scss style.css</code> which works perfectly with content in the included files. This suggests to me a problem with the gulp sass plugin itself.</p>
  
  <p>The relevant snippets from gulpfile.js:</p>
  
  <pre><code>var gulp = require('gulp');
  var sass = require('gulp-sass');
  
  // Compile sass files
  gulp.task('sass', function () {
      gulp.src('./_/sass/style.scss')
          .pipe(sass())
          .pipe(gulp.dest('./'));
  });
  
  // The default task (called when you run `gulp`)
  gulp.task('default', function() {
    gulp.run('sass');
  
    // Watch files and run tasks if they change
  
    gulp.watch(['./_/sass/style.scss'], function() {
      gulp.run('sass');
    })
  });
  </code></pre>
  
  <p>The full contents of style.scss:</p>
  
  <pre><code>/* RESET */
  @import '_/sass/reset';
  /* TYPOGRAPHY */
  @import '_/sass/typography';
  /* MOBILE */
  @import '_/sass/mobile';
  /* MAIN */
  @import '_/sass/main';
  </code></pre>
