Javascript ExtJS中的评级表

我试图从中复制示例评级表。我不明白为什么会出现这样的错误：

[ERR] BUILD FAILED
[ERR] com.sencha.exceptions.ExBuild: Failed to find any files for C:\users\Diederiksj\Desktop\FreshApp\classic\src\view\form\RatingForm.js::ClassRequire::Ext.ux.rating.Picker

当我查看approtDirectory/ext/packages/ux/classic/src/rating时，Picker.js文件就在那里，它是在生成应用程序时由ExtJS自动创建的。下面是我试图要求Picker类的类的摘录：

Ext.define('FreshApp.view.form.RatingForm', {
    extend: 'Ext.panel.Panel',
    xtype: 'form-rating',

    requires: [
        'Ext.ux.rating.Picker'
    ],

    title: 'Rating Form',
    viewModel: true,

    bodyPadding: 10,
    width: 520,
    height: 500,
    minHeight: 400,
    resizable: true,
    frame: true,
    layout: {
        type: 'vbox',
        align: 'stretch'
    },
    defaultType: 'textfield',

任何帮助都将不胜感激。谢谢。

您需要指定您的应用程序需要ux软件包。您可以通过在app.json中添加以下代码段来实现这一点

"requires": [
    "ux"
],

你的app.js中是否有类似路径：{'Ext.ux'：'path/to/ux/'}你的app.js中是否有类似路径：{'Ext.ux'：'path/to/ux/'}我明天才能重试，但我记得，我没有在app.json中添加任何require语句。如果有效的话，我一定会给你们两个+1。谢谢。我在extjs 4.2.2中找不到app.json，如何在extjs 4.2.2中解决这个问题？我明天才能重试，但我记得，我没有在app.json中添加任何require语句。如果有效的话，我一定会给你们两个+1。谢谢。我在extjs 4.2.2中找不到app.json，如何在extjs 4.2.2中解决这个问题？
