问题描述：
我使用requirejs+angularjs+ngMessages参照官方文档写了一个校验的DEMO，但是下图中$error的错误提示正确，但是
<p ng-message="myForm.myName.$error" style="color:maroon">
<p ng-message="required">You did not enter a field</p>
<p ng-message="minlength">Your field is too short</p>
<p ng-message="maxlength">Your field is too long</p>
</p>
中提三行错误提示文字，却一直显示。
可以帮助我看一下是哪里出现问题了吗？
代码：
main.js:
requirejs.config({
paths: {
'angular': '//ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular.min',
'app': 'app',
'lodash': 'https://cdn.jsdelivr.net/lodash/4.13.1/lodash.min',
'ngMessages': '//ajax.googleapis.com/ajax/libs/angularjs/1.5.7/angular-messages'
},
shim: {
'angular': {
exports: 'angular'
},
'ngMessages': ['angular'],
'app': ['angular']
}
});
require(['angular','ngMessages',
'app'
], function(angular){
angular.element(document).ready(function(){
angular.bootstrap(document, ['myApp']);
});
