您好，我在通过 $injector 服务进行依赖注入时遇到了一些问题。
我是 Angular 的新手，所以我会从 IoC 容器的角度解释我是如何看待这个的。

首先是问题：$injector 无法解析 $state。

核心.js 

(function() {
    'use strict';
     angular.module('app.core',['ui.router'])
         .config(function($stateProvider,$state){
           // ......
     });
}());

这是错误： 

  Uncaught Error: [$injector:modulerr] Failed to instantiate module app due      to:
  Error: [$injector:modulerr] Failed to instantiate module app.core due to:
  Error: [$injector:unpr] Unknown provider: $state

我认为堆栈跟踪在这里没有太大的相关性......但以防万一我将它发布在问题的底部：

Index.html：我只是想显示我在哪里以及以什么顺序引用我的 .js 文件。

    <head>
    ....  <!-- pointing out that my .js are not here --> 
    </head>
    <body>

        <script src="bower_components/jquery/dist/jquery.js"></script>
        <script src="bower_components/angular/angular.js"></script>
        <script src="bower_components/angular-ui-router/release/angular-ui-router.js"></script>

        <script src="components/core/lib/core.js"></script>
        **<!-- relevant to the EDIT part below -->
        <script src="components/something/something.js"></script>** 
    </body>

据我了解 Angular 的提供者配方：

$stateProvider is the service provider which registers $state service to the IoC($injector) and does so by exposing $get member which the IoC knows to treat in a special way.

如果创建了“$stateProvider”并且可以自行注入它为什么没有向 IoC 注册“$state”服务

编辑：此外，我稍后还有另一个模块接收 $state 服务作为依赖项没有问题。

东西.js 

   (function() {
     'use strict';
      angular.module('app.something',['ui.router'])  
           .config(function($stateProvider, $urlRouterProvider,$state) {
             .... no problem receiving '$state' here
       })       
 }());

编辑 2：我的错，它在任何配置中都不起作用 VISHAL DAGA是正确的。

在配置阶段，它的所有提供者，所以注入 $stateProvider 是正确的但不是 $state。

删除 $state 问题就会消失。

我认为您正在$state与$stateProvider.state. 正确使用见下文

(function() {
    'use strict';
     angular.module('app.core',['ui.router'])
         .config(function($stateProvider){
           $stateProvider
            .state('default', {....
     });
}());
