当我使用Polymer库创建一个新的应用程序时,它会生成一个示例项目。该项目在Dartium中工作正常,但是当我编译它(使用 pub build ),它不工作了。
When I create a new application using the Polymer library, it generates a sample project. The project works just fine in Dartium, but when I compile it (using pub build), it doesn't work anymore.
我得到两个404和一个未捕获的类型错误。
I get two 404's and an uncaught typeerror.
这是我的控制台输出在Chrome。
Here is my console output in Chrome.

These files exist in build/web/packages/, so I'm not sure why I'm getting a 404.
这工作正常,我更新到最新的Dart SDK(开发渠道)。
This worked fine before I updated to the latest Dart SDK (dev channel). Is it just a bug in there, what might be going on?
感谢。
更新:
我看到一个 Dart问题,我遇到了另一个问题,因此我应用了他们的 fix 到示例项目,现在我只得到 Uncaught TypeError 。现在我的输出如下所示:
I saw a Dart issue that I was having another issue with, so I applied their fix to the sample project, and now I only get the Uncaught TypeError. Now my output looks like this:
Uncaught TypeError: Object #<HTMLDocument> has no method 'registerElement' sample.html_bootstrap.dart.js:6518 wi sample.html_bootstrap.dart.js:6518 ei sample.html_bootstrap.dart.js:8949 Ok sample.html_bootstrap.dart.js:8946 QL sample.html_bootstrap.dart.js:2142 aX.vV sample.html_bootstrap.dart.js:725 Vg sample.html_bootstrap.dart.js:587 (anonymous function) sample.html_bootstrap.dart.js:12313 init.currentScript sample.html_bootstrap.dart.js:12293 (anonymous function) sample.html_bootstrap.dart.js:12307 (anonymous function) sample.html_bootstrap.dart.js:12434推荐答案
我通过在聚合物上放置依赖项约束来工作。我的pubspec.yaml文件现在看起来像这样:
I got it to work by placing a dependency constraint on polymer. My pubspec.yaml file now looks like this:
name: sample description: A sample Polymer application dependencies: browser: any polymer: "0.9.5" transformers: - polymer: entry_points: web/sample.html更多推荐
聚合物+ Dart2js不工作
