确定。这是我的最后一招，直到翻转桌子并向Polymer告别。在过去的3天里，我一直在尝试在聚合物中做一些基本的东西，但我还没有能够这样做。在包括一些纸质元素和缓存（显然甚至没有从Chrome的工具箱中禁用它）之间似乎工作了）我不知道哪个是给我最头疼的人。我也没办法调试项目。足够的咆哮......
我开始最终掌握了这个库，直到我尝试使用<paper-dropdown-menu>和从github下载的自定义元素：<simple-slider>。
简单滑块似乎不起作用（没有正确显示轮播），而纸张下拉菜单则不选择该项目。
已成功引用所有依赖项（使用Visual Studio代码检查），并且还包含webComponents polyfill。
以下是我的主要.html文件：

BTW：我尝试重新安装所有的凉亭套餐，但它没有用。尝试将最新的Polymer解压缩到bower_components文件夹中并且无法正常工作。
有什么想法吗？我无法相信它使用起来很痛苦。
答案 0 :(得分：1)
简单滑块似乎不起作用（没有正确显示轮播）
我假设你指的是polymer-simple-slider。该项目取决于Polymer 0.2.x，它与最新版本的Polymer（撰写本文时为1.10.1）不兼容。如果您对升级该元素感兴趣，可以按照migration guide进行操作。元素的来源看起来非常简单，升级IMO也不会花费太多精力。
纸张下拉菜单不会选择该项目。
请澄清你的意思。选择在这里工作正常：
