Debugging 在AngularJS应用程序中查找错误行

我刚开始玩AngularJS，下面是我的错误

Error: Argument '?' is not a function, got Object
at assertArg (http://localhost/angular/project/scripts/vendor/angular.js:1039:11)
at assertArgFn (http://localhost/angular/project/scripts/vendor/angular.js:1049:3)
at http://localhost/angular/project/scripts/vendor/angular.js:4802:9
at http://localhost/angular/project/scripts/vendor/angular.js:4384:17
at forEach (http://localhost/angular/project/scripts/vendor/angular.js:137:20)
at nodeLinkFn (http://localhost/angular/project/scripts/vendor/angular.js:4369:11)
at compositeLinkFn (http://localhost/angular/project/scripts/vendor/angular.js:4015:15)
at compositeLinkFn (http://localhost/angular/project/scripts/vendor/angular.js:4018:13)
at publicLinkFn (http://localhost/angular/project/scripts/vendor/angular.js:3920:30)
at update (http://localhost/angular/project/scripts/vendor/angular.js:14202:11) 

现在，我的问题是：有没有办法在.js文件中找到发生错误的行？ 在引发异常时，我在angular.js文件中获得了行号，但有太多的文件 可能会发生错误

我尝试使用AngularJS Batarang，但这更多是为了调试语义错误，而不是语法错误

谢谢。

如果您链接到可能导致此错误的js文件，将会更容易

从angular.js源代码中， 这看起来像是实例化控制器的问题

下面是导致断言失败的一行：

/**
 * @ngdoc function
 * @name ng.$controller
 * @requires $injector
 *
 * @param {Function|string} constructor If called with a function then it's considered to be the
 *    controller constructor function. Otherwise it's considered to be a string which is used
 *    to retrieve the controller constructor using the following steps:
 *
 *    * check if a controller with given name is registered via `$controllerProvider`
 *    * check if evaluating the string on the current scope returns a constructor
 *    * check `window[constructor]` on the global `window` object
 *
 * @param {Object} locals Injection locals for Controller.
 * @return {Object} Instance of given controller.
 *
 * @description
 * `$controller` service is responsible for instantiating controllers.
 *
 * It's just a simple call to {@link AUTO.$injector $injector}, but extracted into
 * a service, so that one can override this service with {@link https://gist.github.com/1649788
 * BC version}.
 */
return function(constructor, locals) {
  if(isString(constructor)) {
    var name = constructor;
    constructor = controllers.hasOwnProperty(name)
        ? controllers[name]
        : getter(locals.$scope, name, true) || getter($window, name, true);

=======>assertArgFn（构造函数，名称，true）； }

无法找到控制器的构造函数。

是的，你是对的，我省略了控制器名称为什么没有人对此进行投票？在过去，我从不需要行号，因为我本质上知道我的代码，知道哪里会发生问题。然而，试图将代码从一个系统集成到另一个系统，我现在需要从控制台和angular中的错误中获得更好的信息是没有用的；过了一段时间，您就知道应该首先在哪里查找这些不太具有表现力的错误。不过，你提出的问题很好。我现在还不知道有什么方法可以做到这一点：（另外，Batarang在这里也没有任何帮助。它的主要用途是检查范围继承。

  return $injector.instantiate(constructor, locals);
};
