gulp-sass not compiling sass files - sass

Question

I'm actually trying to build a gulp planning to do web related stuff, like compile sass, minify css, uglify javascript and so on. But I'm really having troubles with sass.
Here's a sample of my code :
gulp.task('compile-sass', function() {
gulp.src(buildType+config.path.sass+"/main.sass")
.pipe(compass({
css: 'css',
sass: 'sass'
}))
.pipe(gulp.dest(buildType+config.path.css+"/test"));
});
So I'm using compass here because i only have *.sass files and no .scss so gulp-sass wouldn't work for me. Therefore, I'm asking if anyone could give me a hint of why this task doesn't work. Here's what my console returns :
[gulp] Starting 'compile-sass'...
[gulp] Finished 'compile-sass' after 6.11 ms
[gulp] You must compile individual stylesheets from the project directory.
events.js:72
throw er; // Unhandled 'error' event
^
[gulp] Error in plugin 'gulp-compass': Compass failed
at Transform.<anonymous> (/Users/myusername/node_modules/gulp-compass/index.js:37:28)
at ChildProcess.<anonymous> (/Users/myusername/node_modules/gulp-compass/lib/compass.js:136:7)
at ChildProcess.EventEmitter.emit (events.js:98:17)
at maybeClose (child_process.js:753:16)
at Socket.<anonymous> (child_process.js:966:11)
at Socket.EventEmitter.emit (events.js:95:17)
at Pipe.close (net.js:465:12)
I know I'm not using any config.rb, but two things :
1) I found no example of such files
2) gulp-compass doc gives example without such a file so I assume it's optional
Thanks in advance.

Thanks to SteveLacy i could manage to fix this.
If you only have .sass files, and no .scss, you need to use gulp-ruby-sass instead of gulp-compass or gulp-sass. Here is a sample of my working code :
var sass = require('gulp-ruby-sass');
gulp.task('compile-sass', function() {
gulp.src(path/to/your/sass/folder/main.sass")
.pipe(sass())
.pipe(gulp.dest('path/to/your/css/folder));
});

The most basic and simple way is:
var sass = require('gulp-ruby-sass');
gulp.task('styles', function() {
gulp.src('sass/*.scss')
.pipe(sass({
noCache : true,
style : "compact"
}))
.pipe(gulp.dest('css'));
});

The newest version of node-sass which is used by gulp-sass supports sass and scss syntax.
https://github.com/sass/node-sass/releases
or the latest release at this moment
https://github.com/sass/node-sass/releases/tag/v0.9.3
node-sass is using libsasss
https://github.com/sass/libsass/releases
Look at their 2.0 release notes.

I know this may not be the correct place for this answer, but there wasn't much on Google for people with gulp-ruby-sass errors.
For anyone receiving an error "source does not match any files." Be sure to make sure the path(s) you place within gulp.src() have at least 1 sass (or scss) file within them.
In my situation, I had 3 paths for the task and only 1 of the paths was completely empty. By adding a blank file (_fake.scss) to that path the error was fixed.
Hope this helps someone!

Newer versions of node-sass (and therefore gulp-sass, which is just a thin wrapper around node-sass) handle both sass and scss syntax, and decides which syntax to use by reading the file extension.
Here is a demonstration of a gulp file which handles both scss and sass syntax (not that you'd want that in your project):
var sass = require('gulp-sass');
sass.compiler = require('node-sass');
gulp.task('my-sass-task', function () {
return gulp.src('styles/**/*.sass') // note file ext
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('static'));
});
gulp.task('my-scss-task', function () {
return gulp.src('styles/**/*.scss') // note file ext
.pipe(sass().on('error', sass.logError))
.pipe(gulp.dest('static'));
});
This doesn't seem to be documented anywhere easy to find, I just happened to stumble on it.
Side note: I was wooed by sass but think I'll be moving to scss instead. This SO question has a lot of useful information in the answers if you're hovering over which to choose.
