我在尝试在模拟器或设备中使用离子Cordova运行示例应用程序“选项卡”时遇到问题。
我正在使用Ubuntu 18.04，并已安装java sdk，android studio，node.js和所有内容。我需要一些帮助，因为我可以找到有关此问题的信息。
我收到以下控制台消息：

最佳答案
[INSTALL_FAILED_UPDATE_INCOMPATIBLE：软件包io.ionic.starter签名与以前安装的版本不匹配；忽略！]
您的软件包名称现在为“ io.ionic.starter”
您的构建成功，但是您已经安装了具有相同封装名称的apk，因此请在cofig.xml第2行中更改您的应用程序软件包名称
