Error after using ngAnimate: TypeError: Cannot read property 'ng-scope' and 'col-sm-6' of undefined

Error after using ngAnimate: TypeError: Cannot read property 'ng-scope' and 'col-sm-6' of undefined

我已将 angular 动画添加到我的项目中。我只把它放在我的 index.html 和 app.js 上。我错过了什么吗?提前致谢

Index.html

<script src="http://code.angularjs.org/1.2.1/angular-animate.js"></script>

App.js

angular.module('portfolio', ['ui.bootstrap','ui.router', 'ngAnimate', 'service', 'ctrl'])

控制台:错误

这个问题看起来和这个很相似post 该建议似乎指向 angular 和 angular 动画模块

之间的不匹配

我遇到了同样的错误,解决方案是 http.所以我升级了版本,我用这个 link 代替。希望对您有所帮助
