javascript – angular错误：$injector：modulerr模块错误

我得到的错误是错误：$inject：modulerr模块错误

这是我收到的错误报告：link

任何想法可能是什么问题？我实际上是从他们的示例网站上复制粘贴.

这是代码：

angular.module('MyApp',['ngMaterial','ngMessages','material.svgAssetsCache'])

.controller('AppCtrl',function($scope) {

});

.buttondemoBasicUsage section {
  background: #f7f7f7;
  border-radius: 3px;
  text-align: center;
  margin: 1em;
  position: relative !important;
  padding-bottom: 10px; }

.buttondemoBasicUsage md-content {
  margin-right: 7px; }

.buttondemoBasicUsage section .md-button {
  margin-top: 16px;
  margin-bottom: 16px; }

.buttondemoBasicUsage .label {
  position: absolute;
  bottom: 5px;
  left: 7px;
  font-size: 14px;
  opacity: 0.54; }
