After configuration gulpfile.js with plumper I got this error:

this is part of my gulpfile.js:

```
.pipe(function() {
return gulpif('*.scss', compass({
css: 'dist/styles/',
sass: 'assets/styles/',
image: 'dist/images/',
}))
.on('error', function(err) {

});
})
```

and in my main.scss

```
@import "compass";
```

How I import compass and compass css3 rules into my .scss files?

After configuration gulpfile.js with plumper I got this error

```
error assets/styles/main.scss (Line 54: File to import not found or unreadable: compass.
```

Start by inspecting gulpfile.js and the main.scss import shown in the issue, then run the Gulp configuration to reproduce the Compass resolution error. Done means the existing SCSS import no longer reports “File to import not found or unreadable: compass” and the stylesheet compilation completes.
