具有此名称的控制器未在angularjs ngroute中注册

我的布局中的Angularjs控制器使用html代码：

<div class="container body-content" ng-app="MyApp">
    <br />
    <br />
    <br />
    <div style="float:right;">
        <a href="#" class="btn btn-danger">Sign Out</a>
    </div>

    @RenderBody()
    <hr />
</div>

<script>
    (function () {

        var app = angular.module('MyApp',['ngRoute',"ngStorage"]);  

        app.controller('myctrllayout',function ($scope) {  

        });
    })();
 </script>

这是我的欢迎页面：

<div ng-controller="welcome">

</div>
<script>
    angular.module('MyApp',[]) 
    .controller('welcome',function ($scope) { 

    });
</script>

当我运行代码时,我收到以下错误

Error: $controller:ctrlreg A controller with this name is not
registered.

The controller with the name ‘welcome’ is not registered.

当我将我的应用程序从(‘MyApp’,[])更改为(‘MyApp’)时：

Module ‘MyApp’ is not available! You either misspelled the module name
or forgot to load it. If registering a module ensure that you specify
the dependencies as the second argument.
