How to setup paths in sass/scss?

Question

css

The first question is that the dependencies are in the root directory in bower_components, is it possible to somehow configure sass (gulp-sass), so that instead of '../../bower_components/
dependence.sass" I should just write dependence.sass ?
The second question is me .sass and .css lie side by side, how to tell the compiler that I am importing another .sass file into the .sass file without specifying the extension, I mean a file with the .sass extension
? or .sass

Answer 1

In the galpa, path is set at the beginning.
Watch the video tutorial from loftblog on galp .. everything is very clear there. And about bower in the same place

Answer 2

gulp.task('sass', function () {
  gulp.src(<path_to_sass_files>)
    .pipe(
      sass({
        includePaths: [],
        imagePath: <path_to_img>
      })
      .on('error', sass.logError))

    .pipe(gulp.dest(paths.css_dir));
});
