I have node-sass installed and it works fine. I installed node-bourbon. I read this: https://github.com/lacroixdesign/node-bourbon but am not sure what my sass config file is. In my gulpfile.js sass task looks like: `gulp.task('styles', function() { gulp.src('resources/assets/sass/**/*.sass') .pipe(sass().on('error', sass.logError)) .pipe(sass({ includePaths: require('node-bourbon').includePaths })) .pipe(gulp.dest('public/css/')); });` Where exactly is this file so that I can use the includePaths snippet?
