gulp-ruby-sass unable to import files

Question

I am trying to create a gulp-ruby-sass task however i am seeing the following error:

[17:32:34] gulp-ruby-sass: error ./styles.scss (Line 1: File to import not found
or unreadable: header.scss.
Load path: C:/Users/nassi/AppData/Local/Temp/gulp-ruby-sass)

My project structure:

app
    assets
        css
            _header.scss
            _home.scss
            _navigation.scss
            _buttons.scss
            _dialogs.scss
            styles.scss

Within styles.scss i have:

@import "header.scss";
@import "home.scss";
@import "navigation.scss";
@import "buttons.scss";
@import "dialogs.scss";

My gulp tasks:

var paths = {
    sass: ['assets/css/styles.scss']
};

// SASS task
gulp.task('sass', function () {
    gulp.src(paths.sass)
      .pipe(sass())
      .pipe(concat('all.min.css'))
      .pipe(gulp.dest('assets/css/'));
});

My newly created all.min.css shows:

/*
Syntax error: File to import not found or unreadable: header.scss.
              Load path: C:/Users/nassi/AppData/Local/Temp/gulp-ruby-sass
        on line 1 of ./styles.scss

1: @import "header.scss";
2: @import "home.scss";
3: @import "navigation.scss";
4: @import "buttons.scss";
5: @import "dialogs.scss";

You must use the loadPath option like this:

// SASS task
gulp.task('sass', function () {
    gulp.src(paths.sass)
        .pipe(sass({
            loadPath : __dirname + paths.sass
        }))
        .pipe(concat('all.min.css'))
        .pipe(gulp.dest('assets/css/'));
});

It's necessary in newer versions of gulp-ruby-sass.

The SASS-partials you can import without any suffix:

@import "header";
@import "home";
@import "navigation";
@import "buttons";
@import "dialogs";
