错误：角度控制器的[ng：areq]

Question

这是一个很长的路，但是以前有人见过这个错误吗？我正在尝试使用express，angular和mongoDB添加“
Transporters”。每当我访问由transporters控制器控制的页面时，都会收到此错误：

Error: [ng:areq] http://errors.angularjs.org/1.2.12/ng/areq?p0=TransportersController&p1=not%20aNaNunction%2C%20got%20undefined

运输者控制器如下所示：

'use strict';

angular.module('mean.transporters').controller('TransportersController', ['$scope', '$routeParams', '$location', 'Global', 'Transporters', function ($scope, $routeParams, $location, Global, Transporters) {
    $scope.global = Global;

    $scope.create = function() {
        var transporter = new Transporters({
            name: this.name,
            natl_id: this.natl_id,
            phone: this.phone
        });
        transporter.$save(function(response) {
            $location.path('transporters/' + response._id);
        });

        this.title = "';
        this.content = "';
    };

    $scope.remove = function(transporter) {
        if (transporter) {
            transporter.$remove();

            for (var i in $scope.transporters) {
                if ($scope.transporters[i] === transporter) {
                    $scope.transporters.splice(i, 1);
                }
            }
        }
        else {
            $scope.transporter.$remove();
            $location.path('transporters');
        }
    };

    $scope.update = function() {
        var transporter = $scope.transporter;
        if (!transporter.updated) {
            transporter.updated = [];
        }
        transporter.updated.push(new Date().getTime());

        transporter.$update(function() {
            $location.path('transporters/' + transporter._id);
        });
    };

    $scope.find = function() {
        Transporters.query(function(transporters) {
            $scope.transporters = transporters;
        });
    };

    $scope.findOne = function() {
        Transporters.get({
            transporterId: $routeParams.transporterId
        }, function(transporter) {
            $scope.transporter = transporter;
        });
    };
}]);

在我看来，我调用该列表并创建方法。他们产生上述错误

我从ng：areq的有角文档中得到了这个，尽管仍然不知道发生了什么

AngularJS经常断言，使用辅助函数会存在某些值并且是真实的。如果断言失败，则会引发此错误。要解决此问题，请确保声明所期望的值已定义且正确。

这是调用控制器的视图public/views/transporters/list.html：

<section data-ng-controller="TransportersController" data-ng-init="find()">
    <ul class="transporters unstyled">
        <li data-ng-repeat="transporter in transporters">
            <span>{{transporter.created | date:'medium'}}</span> /
            <h2><a data-ng-href="#!/transporters/{{transporter._id}}">{{transporter.name}}</a></h2>
            <div>{{transporter.natl_id}}</div>
            <div>{{transporter.phone}}</div>
        </li>
    </ul>
    <h1 data-ng-hide="!transporters || transporters.length">No transporters yet. <br> Why don't you <a href="/#!/transporters/create">Create One</a>?</h1>
</section>

转运服务代码：

angular.module('transporterService', [])
    .factory('Transporter', ['$http', function($http){
        // all return promise objects
        return {
            get: function(){
                return $http.get('/api/transporters');
            },
            create: function(transporterData){
                return $http.post('/api/transporters', transporterData);
            },
            delete: function(id){
                return $http.delete('/api/transporters/'+id);
            }
        };
    }]);

Answer 1

我曾经遇到此错误。问题是我在两个地方用不同的参数定义了angular.module（）。

例如：

var MyApp = angular.module('MyApp', []);

在其他地方，

var MyApp2 = angular.module('MyApp', ['ngAnimate']);
