离子:无法实例化模块 ngCordova

ionic: Failed to instantiate module ngCordova

这是我在安装地理定位插件和 ngCordova 后得到的错误:

E/AndroidProtocolHandler: Unable to open asset URL: file:///android_asset/www/lib/ngCordova/dist/ng-cordova.js
D/JsMessageQueue: Set native->JS mode to OnlineEventsBridgeMode
E/ConnectivityManager.CallbackHandler: callback not found for RELEASED message

            Error: [$injector:nomod] Module 'ngCordova' 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.

我已经运行执行了以下命令:

C:\Users\G\takeaway>ionic plugin add cordova-plugin-geolocation

我按照文档包含了文件。我还在我的代码中包含了该模块:

var app = angular.module('restaurant', ['ionic', 'ngCordova', 'firebase']);

ngCordova 文件存在于此位置:

C:\Users\G\takeaway\www\lib\ngCordova\dist

这是我的代码:

我已经解决了这个问题。必须将 ngCordova 目录复制到:

C:\Users\G\takeaway\platforms\android\assets\www\lib
