Webpack捆绑导致未知提供程序$ injector / unpr错误

未知提供者-NavigationCtrl，以矩形显示

我目前正在处理我的旧项目，以使它们作为一次小型重构练习能够再次完全正常工作，并且遇到了一些不再编译的AngularJS代码。我相信这取决于更新的依赖关系，因为我已经至少三年没有更改此源代码的功能了。

我遇到的问题是：

  

angular.js：15567错误：[$ injector：unpr]未知提供程序：AProvider <-A <-NavigationCtrl   https://errors.angularjs.org/1.7.8/$injector/unpr?p0=AProvider%20%3C-%20A%20%3C-%20NavigationCtrl

我认为这是注射问题。我正在尝试注入Angular不知道的东西。有点困惑，因为我已经有一段时间没有使用AngularJS了（使用过Angular 2 +）。

我的app.js文件如下：

angular.module('qaDashboard', ['restangular'])
    .run(['$anchorScroll', function ($anchorScroll) {
        $anchorScroll.yOffset = 85;   // always scroll by 50 extra pixels
    }]);

angular.module('qaDashboard').controller('NavigationCtrl', function ($scope, $location, $anchorScroll) {
    $scope.scrollTo = function (id) {
        $location.hash(id);
        $anchorScroll();
    };
});

// Environment
require('../components/environments/script.js');
require('../components/environments/style.scss');

// Feature
require('../components/features/script.js');
require('../components/features/style.scss');

// Day
require('../components/days/script.js');
require('../components/days/style.scss');

// Hour
require('../components/hours/script.js');

// Report Data (URL & JSON)
require('../components/report/script.js');
require('../components/report/style.scss');

// Index Style
require('../stylesheets/style.scss');

我的index.html看起来像这样：

<!DOCTYPE html>
<html ng-app="qaDashboard">

<head>
    <title>DASHBOARD</title>
    <script src="/node_modules/angular/angular.js"></script>
    <script src="/node_modules/lodash/lodash.js"></script>
    <script src="/node_modules/restangular/src/restangular.js"></script>
    <script src="/javascripts/app.bundle.js" type="text/javascript"></script>

<body>
    <div class="navbar">
        <p>Regression Test Dashboard</p>
        <div ng-controller="NavigationCtrl" class="navbarAlign">
            <a ng-click="scrollTo('Dev')" class="btn">Dev</a>
            <a ng-click="scrollTo('QA')" class="btn">QA</a>
            <a ng-click="scrollTo('Staging')" class="btn">Staging</a>
            <a ng-click="scrollTo('Staging_EMEA')" class="btn">Staging EMEA</a>
            <a ng-click="scrollTo('Production')" class="btn">Production</a>
            <a ng-click="scrollTo('Production_EMEA')" class="btn">Production EMEA</a>
            <!--<a class="btn">[Do stuff]</a>-->
        </div>
    </div>

    <environments>

    </environments>
</body>

</html>

我尝试删除单个控制器，但没有用。我在这里错过明显的东西吗？自从我上次使用此代码以来，语法/ API发生了很大变化吗？

app,js文件被webpack捆绑-如果这是问题的根源，则不知道。我知道一个事实，就是这段代码以前工作得很好。我只是觉得我缺少一些琐碎的东西，事实证明这很难发现。

我的package.json-如果有帮助：

    "webpack": "^4.36.1"
  }
}

编辑：

我已经尝试过了：

angular.module('qaDashboard', ['restangular'])
    .controller('NavigationCtrl', function ($scope, $location, $anchorScroll) {
        $scope.scrollTo = function (id) {
            $location.hash(id);
            $anchorScroll();
        }
            .run(['$anchorScroll', function ($anchorScroll) {
                $anchorScroll.yOffset = 85;   // always scroll by 50 extra pixels
            }])
    });

没有运气。

编辑2：

我只是用以下代码尝试了georgeawg的响应：

angular.module('qaDashboard', ['restangular'])
    .controller('NavigationCtrl', ["$scope", "$location", "$anchorScroll",
        function ($scope, $location, $anchorScroll) {
            $scope.scrollTo = function (id) {
                $location.hash(id);
                $anchorScroll();
            }
        }]);

// Environment
require('../components/environments/script.js');
require('../components/environments/style.scss');

// Feature
require('../components/features/script.js');
require('../components/features/style.scss');

// Day
require('../components/days/script.js');
require('../components/days/style.scss');

// Hour
require('../components/hours/script.js');

// Report Data (URL & JSON)
require('../components/report/script.js');
require('../components/report/style.scss');

// Index Style
require('../stylesheets/style.scss');

我现在遇到一个angular.js:15567 Error: [$injector:unpr] Unknown provider: AProvider <- A问题。

我的组件如下所示：

angular.module('qaDashboard').component('environments', {
    controller: function (Restangular) {
        this.$onInit = () => {
            Restangular.one('environments').get().then((response) => {
                this.environments = response.environments;
            });
        }
    },
    template: require('./template.html'),

}).filter('formattedEnvironment', () => {
    return (item) => {
        return item.replace('-', ' ')
                   .replace('_', ' ')
                   .replace('_', ' ')
                   .replace('_', ' ');
    }
});

<div id="{{environment}}" ng-repeat="environment in $ctrl.environments" class="borderedHolder">
    <h1>{{environment | formattedEnvironment}}</h1>
    <features environment='environment' >

    </features>
</div>

（有多个组件，它们都使用Restangular，就像上面的^

编辑3：我已经尝试过：

具有：angular.js:15567 Error: [$controller:ctrlreg] The controller with the name 'EnvironmentsController' is not registered. 

angular.module('qaDashboard').component('environments', {
    controller: 'EnvironmentsController', ['Restangular', function (Restangular) {
        this.$onInit = () => {
            Restangular.one('environments').get().then((response) => {
                this.environments = response.environments;
            });
        }
    },
        template]: require('./template.html'),

})

答案 0 :(得分：0)

使用Inline Array Annotation：

angular.module('qaDashboard', ['restangular'])
.controller('NavigationCtrl', ["$scope","$location","$anchorScroll",
  function($scope, $location, $anchorScroll) {
    $scope.scrollTo = function (id) {
        $location.hash(id);
        $anchorScroll();
    }
}]);

更新

为帮助您在丑陋之前发现此类问题，请使用严格依赖注入。

从文档中：

  

使用严格依赖注入

     

您可以在与ng-strict-di相同的元素上添加ng-app指令，以选择进入严格的DI模式：

<!doctype html>
<html ng-app="myApp" ng-strict-di>
<body>
  I can add: {{ 1 + 2 }}.
  <script src="angular.js"></script>
</body>
</html>
     

每当服务尝试使用隐式注释时，严格模式都会引发错误。

请您根据我的修改3向我展示？

app.component('environments', {
    ̶c̶o̶n̶t̶r̶o̶l̶l̶e̶r̶:̶ ̶f̶u̶n̶c̶t̶i̶o̶n̶(̶R̶e̶s̶t̶a̶n̶g̶u̶l̶a̶r̶)̶ ̶{̶
    controller: ["Restangular", function(Restangular) {
        this.$onInit = () => {
            Restangular.one('environments').get().then((response) => {
                this.environments = response.environments;
            });
        }
    ̶}̶,̶
    }],
    template: require('./template.html'),    
})

注意：：如果您打算minify代码，则您的服务名称将被重命名并破坏您的应用程序。
