我知道ionic serve无法使用cordova插件，在尝试使用cordova插件之前，我总是检查我是否处于cordova环境中。
说完之后。我不知道为什么会收到这个错误：
ERROR Error: Uncaught (in promise): cordova_not_available

我不确定它是如何开始的，我认为它与ionic livereload workaround有关，但我更新了我的应用脚本版本并重新安装了所有node_modules，plugins和platforms问题仍然存在。

@ toby-okeke关于在platform.ready之前调用本机插件的评论之后我重新检查了我的代码并且所有操作都正确完成但是statusBar和appVersion插件看起来不正常当没有cordova.js时。而其他插件则显示如下警告：
Native：尝试调用PluginName.prepare，但Cordova不可用。确保包含cordova.js或在设备/模拟器中运行
statusBar和appVersion从我的问题中抛出错误。我将它们包裹在if(this.platform.is("cordova"))中，错误消失了。
