dart - 更新 Dart SDK 版本 0.3.2.0_r17657 后出现 html5lib 错误

Question

当我运行 Web 组件的 build.dart 时，未创建 out 文件夹，并且收到此错误:

SEVERE web/main.html: exception while reading file, original message:
 AsyncError: ''package:html5lib/dom.dart': Error: line 91 pos 51: type 'LinkedHashMap' is not loaded
  LinkedHashMap<dynamic, String> attributes = new LinkedHashMap();
malformed type used.'

有人遇到同样的问题吗？

更新:感谢您的回答。但是，我运行 pub update 现在如果我运行 build.dart 文件，结果是:

Answer 1

我刚刚经历过这个。这是因为您拥有的软件包尚未更新。确保您使用的是每个软件包的最新版本，然后运行 ​​pub update。

就我而言，我使用的是旧版本的web-ui，它使用了旧版本的html5lib包。我更新了 web-ui 并且一切正常。

就像 Florian 在另一个答案中所说的那样，这是由一个已移动到另一个库的类引起的。
