我尝试安装angular-messages但是收到以下错误消息：
$ bower install angular-messages --save
继承我的json文件：
{
"name": "HelloIonic",
"private": "true",
"devDependencies": {
"ionic":"driftyco/ionic-bower#1.3.1"
},
"dependencies": {
"ion-datetime-picker": "^0.3.1",
"ionic-datepicker": "^1.2.1",
"angular-bootstrap-toggle-switch": "^0.5.6"
}
}
