Question

我的 Polymer.dart 网络应用程序，在Dartium中正常工作，在使用pub build --mode=debug使用dart2js编译并在Chrome中加载时，会出现以下错误（重复7次）。 / p>

由于源地图似乎无法正常工作（它们已在Chrome中启用，我有.map文件），我甚至不知道我的代码的哪一部分导致了此问题。

我已尝试将interop.js包括在dart.js之前，as the docs say之后，as this issue之后。

Answer 1

看起来像是dart2js中的一个错误。请提交一个问题，理想情况下是一个可重现的测试用例。

Answer 2

pub upgrade修复了它。事实证明，有些东西取代了我在0.8.10 + 4时使用的聚合物0.9.5。很奇怪。对此的解决方案是将聚合物版本设置为＆lt;＆gt;＆gt; = 0.9.5＆＃39;而不是我最后会做的任何事情，但是现在我有兴趣看看它是否会再次发生。

来自dart2js的代码为get $ functions抛出了NoSuchMethodError
