我正在开发一个带有Angular 1.6/MVC 4.6/E.F 6.0的Web应用程序。我还添加了UI-Grid。它运作良好。我正在尝试创建自定义过滤器，就像文档的这一部分一样。我的目标是创建与"年龄"相同的自定义过滤器。它适用于本地，但当我发布 WebApp 时则不然。我有两个错误：
Possibly unhandled rejection: canceled
Error: [$injector:unpr] http://errors.angularjs.org/1.6.2/$injector/unpr?p0=nProvider%20%3C-%20n%20%3C-%20myCustomModalCtrl
我很确定它与我为此自定义过滤器添加的控制器/指令有关。我已经阅读了 Angular JS 帮助页面，但我不知道如何纠正此错误，以及为什么它只能在本地工作

不确定这是否有帮助，但您的问题可能与myCustomModalCtrl控制器的声明有关。与其他声明相比，此声明缺少注入服务的完整限定声明：
PrintersApp.controller('myCustomModalCtrl', function ($scope, $compile, $timeout) { [..] });
应该是：
PrintersApp.controller('myCustomModalCtrl', ['$scope', '$compile',
'$timeout', function ($scope, $compile, $timeout) { [..] }]);
当代码缩小时，参数$scope将重命名为，例如，a。这将导致您收到的错误，因为$injector中没有声明名为a的服务。
为了避免这个问题，我们必须告诉$injector为我们在控制器中请求的每个参数注入正确的服务名称。
