Question

我正在尝试运行一个有角度的网页应用。我克隆了已确认的工作项目，但是当我运行pub get时出现以下错误：

/usr/lib/dart/bin/pub get
Resolving dependencies...
Got dependencies!
Precompiling dependencies...
Loading source assets...
Loading angular, sass_builder and dart_to_js_script_rewriter transformers...
Error on line 26, column 5 of ../../.pub-cache/hosted/pub.dartlang.org/angular_components-0.8.0/pubspec.yaml: Error loading transformer: 'package:sass_builder/sass_builder.dart': malformed type: line 34 pos 20: cannot resolve class 'Logger' from 'SassBuilder'
  final _log = new Logger('sass_builder');
                   ^

我的pub.yaml：

# Uncomment the following in sdk 1.24+ to make pub serve

我正在使用飞镖1.24.3 我尝试删除pub-cache，进行缓存修复，甚至重新安装Dart。什么都没有帮助。我在Ubuntu 16.04上工作。请帮忙。

我还可以确认WebStorm的基本项目也不起作用。除了卸载和安装dart之外，我不知道该怎么办...

Answer 1

到目前为止，我已经发现在pub-cache中编辑SassBuilder类可以解决问题。您只需要从此

更改记录器的导入

import 'package:logging/logging.dart';

到此：

import 'package:logging/logging.dart' as Log;

并且还改变了logger构造函数：

final _log = new Logger('sass_builder');

到此：

final _log = new Log.Logger('sass_builder');

我现在不知道更好的解决方案。

Answer 2

这是sass-builder中的问题。要解决此问题，请在 pubspec.yaml 中使用sass_builder: ^1.1.5或更高版本。这是pull request修复。

Answer 3

同时，您可以将sass 1.0.0-beta.5.3添加到pubspec.yaml并运行pub get

dependency_overrides:
   sass: 1.0.0-beta.5.3

Dart SassBuilder无法找到Logger
