看起来dart2js正在尝试编译bootstrap的css文件。我试图谷歌这个问题，但我找不到任何有用的东西。我猜那是因为我不确定我应该用什么谷歌搜索。
我的上一个项目很顺利，因为我在这个项目中使用了所有相同的库，我只是复制了pubspec.yaml。

这基本上是angular2入门page上使用的那个，但是添加了平台指令。

我只使用了dart几周，但我遵循了他们的目录布局guide。

我列出了bootstrap-3.3.6目录下的所有内容。没有此类文件web/css/bootstrap-3.3.6/css/bootstrap.min.css.dart或web/css/bootstrap-3.3.6/css/bootstrap.min.css.shim.dart
即使pub build似乎不适用于此项目，pub serve也没有任何问题。
答案 0 :(得分：3)
我会尝试排除Angular2转换器的web/css目录：
transformers:
- angular2:
$exclude: ['web/css/**']
entry_points: web/main.dart
platform_directives:
- package:angular2/common.dart#CORE_DIRECTIVES
- package:angular2/common.dart#FORM_DIRECTIVES
- dart_to_js_script_rewriter
