ダーツでコンパイル中のエラー

Question

私は地元のAngluarDartでダーツを持っています。

のUbuntu 16.04.2 DartSdkのv1.23.0

$ pub serve 
Loading source assets... 
Loading angular2, dart_to_js_script_rewriter and dart_sass_transformer 
transformers... (3.4s) 
Serving xxx web on http://localhost:8080 
Build completed successfully 

罰金を働くようだ。しかし、私は私のブラウザにウェブをロードしようとすると、私はこのエラーを取得する "パブは、サーブ"：

[web] GET Served 3 cached assets. 
[Info from Dart2JS]: 
Compiling xxx|web/main.dart... 
[Error from Dart2JS]: 
web/main.dart: 
The compiler crashed when compiling this element. 
The compiler is broken. 

When compiling the above element, the compiler crashed. 
It is not possible to tell if this is caused by a problem in your program or not. 
Regardless, the compiler should not crash. 

The Dart team would greatly appreciate if you would take a moment to 
report this problem at http://dartbug.com/new. 

Please include the following information: 

* the name and version of your operating system, 

* the Dart SDK build number (build number could not be determined), and 

* the entire message you see here (including the full stack trace 
below as well as the source location above).

もう一度DartSDKを入手しようとしましたが、PATHを改訂しました。

W帽子が問題になることはありますか？

Answer 1

Dart SDKのバージョンを下げて問題を解決しました。 から1.23.0から1.21.1まで

今では、コンプライアントは問題なく仕事をしています。
