Аfter将Dart代码(使用Dart Polymer)编译为JS。我收到以下错误:
Uncaught Exception: The "smoke" library has not been configured.
Make sure you import and configure one of the implementations
(package:smoke/mirrors.dart or package:smoke/static.dart).
有时消息是:
No elements registered in a while, but still waiting on 1 element to be registered. Check that you have a class with an @CustomTag annotation for each of the following tags: 'app-element'
怎么了这是我的代码:
更新:现在，改进了
pub build之后的代码，并且可以正常工作。我更改文件夹/文件结构并将聚合物更新为最新版本。pubspec.yaml
name: app
dependencies:
browser: any
#do not forget update to latest version by running pub update
polymer: any
transformers:
- polymer:
entry_points:
- web/main.html
web / templates / ui-elements.html
<polymer-element name="app-globals"></polymer-element>
<polymer-element name="app-element">
<template>
<link rel="stylesheet" href="/main.css"/>
<content></content>
</template>
<script type="application/dart" src="ui-elements.dart"></script>
</polymer-element>
网站/模板/ui-elements.dart
@CustomTag('app-globals')
class AppGlobals extends PolymerElement{
AppGlobals.created() : super.created();
}
@CustomTag('app-element')
class AppElement extends PolymerElement {
AppElement.created() : super.created();
}
web / main.html (虚拟条目文件)

pub build之后的(入口点)。编译后的真实困惑。如此多的js文件，其中一些文件甚至超过300kb。<!DOCTYPE html><html lang="en"><head><script src="packages/web_components/webcomponents.min.js"></script><script src="packages/web_components/dart_support.js"></script>

最佳答案
使用initPolymer时不需要@whenPolymerReady。整个main()方法在您的示例中是多余的。
您是否在pubspec.yaml的Polymer变压器配置中正确注册了进入页面？
Smoke需要一个变压器，但是如果您正确配置了Polymer变压器，则包括Smoke变压器。
