angularjs 模块注入错误

var app = angular.module('myApp', ['ngLoadScript']);
app.config(function($routeProvider, $controllerProvider, $compileProvider, $filterProvider)
{
app.controllerProvider = $controllerProvider;
app.compileProvider = $compileProvider;
app.routeProvider = $routeProvider;
app.filterProvider = $filterProvider;
});
app.controller('mainController', function($scope) { });

上面这段代码写在myApp.js中，为什么运行时显示Uncaught Error: [$injector:modulerr] 错误。我想把controllerProvider保存下来，之后有用。这么做为什么出错？

问题不在$controllerProvider，而在$routeProvider。你看这：

var app = angular.module('myApp', ['ngLoadScript']);

你没有引入ngRoute，却要注入$routeProvider，你觉得能成么?
