聚合物纸张输入不工作

Question

我是聚合物初学者。我安装了 Polymer v1.7，我正在尝试构建一个简单的表单。在我的应用程序中试图输入纸张，但根本没有显示。检查 DOM，注意到元素在那里，但未呈现。并且，在控制台中显示了一些与纸张相关的消息。我决定构建一个全新的基本项目来测试该单个元素，但同样，该元素不起作用并且消息仍然存在。

我当前的代码是：

bower.json

{
    "name": "test001",  
    "main": "index.html",  
    "dependencies": {  
        "polymer": "Polymer/polymer#^1.4.0",  
        "iron-elements": "PolymerElements/iron-elements#^1.0.10",  
        "iron-form": "PolymerElements/iron-form#^1.1.4",  
        "iron-component-page": "PolymerElements/iron-component-page#^1.0.0",  
        "paper-elements": "PolymerElements/paper-elements#^1.0.7"  
    },  
    "devDependencies": {  
        "iron-component-page": "PolymerElements/iron-component-page#^1.0.0",  
        "iron-demo-helpers": "PolymerElements/iron-demo-helpers#^1.0.0",  
        "web-component-tester": "^4.0.0",  
        "webcomponentsjs": "webcomponents/webcomponentsjs#^0.7.0"  
    }  
}

test001-app:

<link rel="import" href="../../bower_components/polymer/polymer.html">  
<link rel="import" href="../../bower_components/paper-input">  
<dom-module id="test001-app">  
    <template>  
        <style>  
            :host {  
            display: block;  
            }  
        </style>  
        <h2>Hello [[prop1]]</h2>  
        <paper-input label="Etiqueta"></paper-input>  
    </template>  
    <script>  
        Polymer({  
           is: 'test001-app',  
           properties: {  
               prop1: {  
                   type: String,  
                   value: 'test001-app',  
               },  
           },  
        });  
    </script>  
</dom-module>

控制台消息：

Behavior Polymer.IronA11yKeysBehavior not found when mixing properties into paper-input! docs.js:126

Behavior Polymer.IronFormElementBehavior not found when mixing properties into paper-input! docs.js:126

Behavior Polymer.IronFormElementBehavior not found when mixing properties into paper-textarea! docs.js:126

Behavior Polymer.IronA11yKeysBehavior not found when mixing properties into Polymer.PaperInputBehavior!

我尝试在打开和关闭纸标签（即：abc）之间放置一些内容并显示出来，但不是作为输入元素（只是作为基本文本）

您对 <paper-input> 的 HTML 导入不正确：

<!-- wrong -->
<link rel="import" href="../../bower_components/paper-input">

应该是：

<link rel="import" href="../../bower_components/paper-input/paper-input.html">
