SASS无法使用Dart DDC进行编译

Question

当我用DDC编译我的web-app时，我得到了以下错误：

SEVERE] build_web_compilers|ddc on package:sass/sass.dartdevc.module (cached):
Error compiling dartdevc module:sass|lib/sass.ddc.js

[error] Target of URI doesn't exist: 'node/interface.dart'. (package:sass/src/importer/node.dart, line 5, col 8)
[error] The exported library ''node/interface.dart'' can't have a part-of directive. (package:sass/src/importer/node.dart, line 5, col 8)
[error] Target of URI doesn't exist: 'io/interface.dart'. (package:sass/src/io.dart, line 7, col 8)
[error] Target of URI doesn't exist: 'io/interface.dart'. (package:sass/src/io.dart, line 12, col 8)
[error] The exported library ''io/interface.dart'' can't have a part-of directive. (package:sass/src/io.dart, line 12, col 8)
[error] Target of URI doesn't exist: 'package:package_resolver/package_resolver.dart'. (package:sass/src/sync_package_resolver.dart, line 1, col 8)

我不太确定我需要什么。我有一个名为compiler-sass.dart的dart文件，其中包含以下代码：

import 'dart:io';
import 'package:sass/sass.dart' as sass;

void main(List<String> arguments) {
  var result = sass.compile(arguments[0]);
  new File(arguments[1]).writeAsStringSync(result);
}

如果我手动编译我的sass文件，它可以工作，但不能使用以下命令：

webdev serve --hot-reload

我的pubspec有以下依赖关系：

dependencies:
  path: ^1.4.1
  sass: ^1.16.1
  vue: ^0.4.1
  build_runner: ^1.1.2
  build_web_compilers: ^1.0.0
  intl: ^0.15.7

这里我漏掉了什么？为什么它不起作用？

https://pub.dartlang.org/packages/sass_builder直接与webdev集成，以增量方式仅构建已更改的内容和浏览器获取的内容。
