虽然我有ui-boostrap安装后，浏览器向我发送错误 Error: [$injector:unpr] Unknown provider: uniqueFilterProvider <- uniqueFilter

html

<section class="footer">
  <div id="explanation" class="container">
    <div ng-repeat="animal in animals | unique: 'animal.domain'" ng-hide="domain" class="panel panel-default">
      <p  class="panel-body">{{animal.domain.name}}</p>
    </div>
  </div>
</section>

我还尝试了唯一值的变体，例如 domain.name和domain ，但它们都会带来相同的错误。

我找到了答案。相反，我们所要做的就是简单地安装精彩的、天才的、不可替代的a8m带有 bower/npm 的 Angular-filter 库，添加到我的依赖项数组 (@Joy) 中，并使用语法 ng-repeat="animal in Animals | unique: 'domain.name'" 一切正常。
