其他人很多都有这个问题为好，但看起来可能通过声明依赖作为一个数组，而不是裸露的功能参数，像这样固定的：

Lots of other people had this problem as well, but looks like it could be fixed by declaring dependencies as an array instead of bare function parameters, like this:

angular.module('my-app').controller('LoginCtrl', [ '$scope', 'HttpService', function($scope, HttpService) { ... }]);

而不是这样的：

angular.module('my-app').controller('LoginCtrl', function($scope, HttpService) { ... });

不过，这并不在我的情况下工作。我检查了我所有的脚本（咖啡和JavaScript的产生以及），它们都使用正确的阵列式的声明。

But it doesn't work in my case. I checked all of my scripts (coffee and generated javascripts as well), they all use the proper array-style declaration.

问题并非来自额外的软件包明显。我试图将所有多余的包引用出来的＆LT; - 鲍尔：JS - ＆GT; 块（这样它们不会被咕噜缩小的），但问题依然遗迹。这意味着，这是我的code惹的祸......不过话又说回来，我已经试过了（好像是）只提供固定，但没有成功。

The problem doesn't come from extra packages apparently. I tried moving all extra package references out of <!-- bower:js --> block (so that they are not minified by grunt), yet the problem still remains. Which means, it's my code to blame... But then again, I've tried the (seems to be) only fix available, to no avail.

任何暗示，甚至在如何正确调试呢？

Any hint, even on how to properly debug this?

在此先感谢！

推荐答案

最后，我已经找到了问题。是的，这是我错过了一个DI错误。

Finally I've found the problem. And yes, it's a DI bug which I missed.

要所有谁可以从相同的头痛是痛苦：阵列格式的声明必须在 $ routeProvider 来完成的解析选项，以及。在我的情况下（前面的CoffeeScript）：

To all who may be suffering from the same headache: array-format declaration must be done in $routeProvider's resolve options as well. In my case (CoffeeScript ahead):

app.config (['$routeProvider', ($routeProvider) ->
  $routeProvider
    .when '/',
      templateUrl: 'views/main.html'
      controller: 'MainCtrl'
      resolve: 
        groups: ['GroupService', (GroupService) ->  # I MISSED THIS
          return GroupService.getAll()
        ]
        entries: ['EntryService', (EntryService) ->  # AND THIS
          return EntryService.getAll()
        ]
    # ...
])

希望这有助于！
