Why doesn't code compile less to CSS?

Question

css

Good evening friends. The trouble is, galp does not convert less to CSS, there were no problems at all with SASS. In the console it says that everything is ok, but the file remains clean

var less = require('gulp-less'),
path = require('path');

gulp.task('less', function () {
    return gulp.src('./less/**/*.less')
      .pipe(less({
        paths: [ path.join(__dirname, 'less', 'includes') ]
      }))
      .pipe(gulp.dest('./app/css'));
  });

  gulp.task('watch',  function() {
    gulp.watch('app/less/**/*.less', ['less']);
});

Answer 1

Perhaps the problem is in the paths parameter, you calculate it based on __dirname, and this is the path to the current file, that is, to the file with the gallp task, and not with the sources.
