Use require.js to manage angular dependencies, and found the following problems (directly upload the code):

The following is main.js:------------------------------------------------- -------

require.config({

paths: {
    "angular": "../vender/angular-1.5.8/angular",
    "jquery": "../vender/jquery-1.11.3",
    "angularRoute": "../vender/angular-1.5.8/angular-route.min",
    "angularResource": "../vender/angular-1.5.8/angular-resource.min",
    "domReady":"../vender/domReady",
},
shim:{
    angular:{
        exports :"angular"
    },
    angularRoute:{
        deps:["angular"]
    },
    angularResource:{
        deps:["angular"]
    }, 
},
waitSeconds: 0

});

require([

'app',
'bootstrap',
],function(app){
'use scrict';
app.config(['$routeProvider',function($routeProvider){
    console.log($routeProvider);
}])

})

The following is app.js:---------------------------------

define(['angular'],

function(angular){
    console.log('app');
    return angular.module('app',[]);
}

);

The following is bootstrap.js:--------------------------------

define(['angular','domReady'],function(angular,domReady){

domReady(function(){
    console.log('boot');
    angular.bootstrap(document,['app']);
})

})

There is no error reported above. The following is the normal operation result:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

When I added the dependent module (angularResource) in app.js as follows:

define(['angular','angularResource'],

function(angular){
    console.log('app');
    return angular.module('app',['ngResource']);
}

);

At this time, an error will be reported: as follows

You can see that the app does not print out, why? Just introduce a module.
If you introduce a dependent app in bootstrap.js: as follows
define(['angular','domReady','app'],function(angular,domReady){

domReady(function(){
    console.log('boot');
    angular.bootstrap(document,['app']);
})

})
will not report an error.
But I don’t understand why introducing an angularResource before will cause an error?
