我正在尝试在Ionic（也是v3）应用程序中使用自定义的Polymer（v3）组件。
如果我与ionic cordova run android一起运行，该组件可以正常工作。
但是当我尝试使用--prod标志运行时，该项目会在我的手机中编译并打开，但它根本不会显示该组件。
chrome检查工具中显示的错误如下：
Uncaught TypeError: Failed to construct 'HTMLElement': Please use the 'new' operator, this DOM object contructor cannot be called as a function.
这是我的package.json：

我尝试将webcomponents添加到我的index.html中，但仍然没有成功。
