That because the unique filter can currently be found as part of AngularJs UI Utils. 因为独特的过滤器目前可以作为AngularJs UI Utils的一部分找到。 To make this work you must include it as an additional reference in your module angular.module('myApp', ['ui', 'ui.filters']); 要使其工作，您必须将它作为附加参考包含在您的模块angular.module('myApp', ['ui', 'ui.filters']);
Hope this help you. 希望这对你有所帮助。

You need to inject 'ui.directives' and 'ui.filters' module to your app 您需要将“ui.directives”和“ui.filters”模块注入您的应用程序
var app = angular.module('myApp',['ui.directive', 'ui.filters']);
Since ui.directives and ui.filters modules are present in AngularUI, you will also need to refer angular-ui.js in your application 由于AngularUI中存在ui.directives和ui.filters模块，因此您还需要在应用程序中引用angular-ui.js
<script src="http://cdnjs.cloudflare.com/ajax/libs/angular-ui/0.4.0/angular-ui.min.js"></script>
Your full code should look something like this 您的完整代码应如下所示

<body ng-app="myApp" ng-controller="myCtrl">
<p ng-repeat="x in persons | unique: 'age'">{{x.name}}</p>
<script>
//App declaration
var app = angular.module('myApp',['ui.directives','ui.filters']);
//Controller Declaration
app.controller('myCtrl',function($scope){
$scope.persons = [{name: "Peter",age:23},{name:"Laila",age:25},{name:"Rosy",age:23}];
});
