运行dart2js.bat时无法解释的错误

Question

试图从我的Dart应用程序中生成JavaScript，会产生以下消息，而不生成JavaScript：

--- Jun 21, 2013 9:50:51 PM Running dart2js... ---
C:\Program Files (x86)\Dart\dart-sdk\bin\dart2js.bat --suppress-warnings 
--out=C:\Users\nledon\dart\UnityPlayer\web\unityplayer.dart.js 
C:\Users\nledon\dart\UnityPlayer\web\unityplayer.dart\Dart\dart-sdk\" was unexpected at this time.

知道这是怎么回事吗？

谢谢。

我将省道编辑器安装移到*C:\Program *，从而解决了这个问题。

Dart编辑器似乎不理解*C:\Program (x86)*路径。
