当我运行我的Web组件的build.dart时,没有创建out文件夹,我收到此错误:
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.'

有没有人有同样的问题?
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:
Uncaught Error: NoSuchMethodError : method not found: 'innerHTML'

答案 0 :(得分:1)
我最近将'LinkedHashMap'从dart:core移到了dart:collection。 您展示的代码仍然希望它在核心。
尝试找到html5lib软件包的更新版本(也许邮件列表知道你可以在哪里下载一个)。
Bob目前正致力于在pub中对dart-sdk进行版本控制。所以希望将来不会出现这样的问题。

我刚刚经历过这个。这是因为您拥有的套餐尚未更新。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web-ui
的旧版本,该版本使用旧版html5lib
包。我更新了web-ui
,事情很有效。
就像弗洛里安在另一个答案中说的那样,这是由一个已搬到另一个图书馆的班级引起的。
