请帮帮我。

这与使用绝对路径还是相对路径有关，这是一个复杂的问题（请参阅 https://github.com/PolymerElements/polymer-starter-kit/issues/919 作为切入点了解更多详细信息）。

为了让事情正常进行，您应该能够更改索引文件中的这一行：

script.src = '/bower_components/webcomponentsjs/webcomponents-lite.min.js';

到

script.src = 'bower_components/webcomponentsjs/webcomponents-lite.min.js';

然而，当运行在 Cordova 上时，您可能需要对您的应用程序路由进行一些更改，但看看这是否能让您入门。
