Почему не выполняется таск clean:dist?

Question

[suprascapularis69]

Здравствуйте, при выполнении таска gulp build выполняются все параллельные таски, но clean:dist нет, в чем может быть дело?

gulp.task('clean:dist', function() {
  return del.sync(['dist/**/*', '!dist/images', '!dist/images/**/*']);
});

gulp.task('build', gulp.parallel('clean:dist', ['sass', 'useref', 'images', 'fonts']));

[23:34:28] The following tasks did not complete: build, clean:dist
[23:34:28] Did you forget to signal async completion?

gulp.task('clean:dist', function() {
  return del(['./dist/**', '!./dist/images/**']);
});

gulp.task('build', gulp.series('clean:dist', gulp.parallel('sass', 'useref', 'images', 'fonts')));

подредактировал, мой косяк. Пропустил gulp.перед parallel

теперь вообще не работает gulp build, выдает ошибку ReferenceError: parallel is not defined
