我与聚合物的1.x一会儿工作,我想从头开始一个项目与聚合物2.0,但我得到了许多错误。我正在构建一个PWA,因为我包含了一个服务工作者和一个manifest.json文件。我得到的错误是,我认为,大多数版本之间的不兼容的,因为他们声称一些类的话(第二个错误等)定义的或不确定的“窗口”对象聚合物2.0错误
适用版本我遵循这个指南(点:升级现有项目)

正如你可以看到应用程序是一个骨架很简单(只是一个测试开始),所以有应该不会有太大得到错误或调查,以找出错误的原因,但我不明白这是什么问题以及如何解决它。任何帮助将不胜感激。
感谢您的文章。你的修补程序是否消除了这两个错误,或者只是第一个?我试图追查第二个错误的原因(在'风格util.js中:243'),其中我看到在不使用'铂sw'的应用程序。 – kjhughes
