【中文标题】找不到变量：设备【英文标题】：Can't find variable: device 【发布时间】：2014-12-07 09:07:40 【问题描述】：我被困在这个 phonegap 项目中。在 android 和 ios = 8.0 上失败。出现一个弹出窗口并显示消息：“”
这是我收到的消息：

【参考方案1】：你需要先安装设备cordova插件。
https://github.com/apache/cordova-plugin-device
命令
cordova plugin add https://github.com/apache/cordova-plugin-device
【讨论】：
我也这样做了。安装插件在 config.xml 文件中添加插件仍然抛出相同的错误。需要您的帮助或检查清单。【参考方案2】：是的，我试过那个 ofc 没用。我发现问题在于你需要为ios编译插件才能使用它。这在 Windows 机器上根本不可能。 有些事情（Windows 用户）需要考虑。
【讨论】：
如何编译插件？以上是关于找不到变量：设备的主要内容，如果未能解决你的问题，请参考以下文章
