android - (节点 :15016) UnhandledPromiseRejectionWarning: Error: adb: Command failed with exit code 1

Question

我在尝试在模拟器或设备中使用 ionic 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 并安装了 java sdk、android studio、node.js 和所有东西。我需要一些帮助，因为我可以找到有关此问题的信息。

我收到了这条控制台消息:

Answer 1

[INSTALL_FAILED_UPDATE_INCOMPATIBLE:包 io.ionic.starter 签名与之前安装的版本不匹配；无视!]

your package name now "io.ionic.starter"

您的构建成功，但您已经安装了一个具有相同包名的 apk，因此请在 cofig.xml 第 2 行中更改您的应用程序包名称
