我正在尝试使用 Kendo UI Angular 指令在本地绑定 DataViz 饼图，但一直收到此错误：

HTML

<div kendo-chart k-options="pie" k-data-source="countries" />

$scope.countries = {
    data: [
        {
            category: "Asia",
            value: 53.8,
            color: "#9de219"
        }, {
            category: "Europe",
            value: 16.1,

$scope.pie = {

检查您的库以确保您使用的是受支持的版本。您使用的是最新版本的 KendoUI 吗？根据KendoUI->Angular repo on GitHub你需要：

• jQuery v1.9.1（不确定是否支持更高版本）
• Angular v1.0.5
• KendoUI vCurrent

我创建了a working example on JSBin 供您查看。代码如下：

<!DOCTYPE html>
<html>
<head>
<meta name="description" content="Angular + KendoUI DataViz" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.0.5/angular.min.js"></script>
<script src="http://cdn.kendostatic.com/2013.3.1119/js/kendo.all.min.js"></script>
<script src="http://rawgithub.com/kendo-labs/angular-kendo/master/build/angular-kendo.min.js"></script>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body ng-app="chart-example">
  <div ng-controller="ChartController">    
    <div kendo-chart k-options="pie" k-data-source="countries" />
  </div>
</body>
</html>

...

var app = angular.module('chart-example', ['kendo.directives']);

function ChartController($scope) {
  $scope.pie = {
    title: {
        position: "bottom",
        text: "Share of Internet Population Growth, 2007 - 2012"
    },
    legend: {
        visible: false
    },
    chartArea: {
        background: ""
    },
    seriesDefaults: {
        labels: {
            visible: true,
            background: "transparent",
            template: "#= category #: #= value#%"
        }
    },
    series: [{
        type: "pie",
        field: "value",
        categoryField: "category"
    }],
    tooltip: {
        visible: true,
        format: "{0}%"
    }
  };

  $scope.countries = {
    data: [
        {
            category: "Asia",
            value: 53.8,
            color: "#9de219"
        }, {
            category: "Europe",
            value: 16.1,
            color: "#90cc38"
        }, {
            category: "Latin America",
            value: 11.3,
            color: "#068c35"
        }, {
            category: "Africa",
            value: 9.6,
            color: "#006634"
        }, {
            category: "Middle East",
            value: 5.2,
            color: "#004d38"
        }, {
            category: "North America",
            value: 3.6,
            color: "#033939"
        }
    ]
  };
}
