我正在尝试运行以下命令：

但我收到以下错误

我尝试删除和添加 android 平台

ionic cordova platform rm android
ionic cordova platform add android

但仍然是同样的错误。任何帮助，将不胜感激。谢谢你。

解决方案

您不必使用--device在手机上运行应用程序，您可以简单地使用：

ionic cordova build android

接着

ionic cordova run android

如果你想检查每个人都会看到的真实结果，那么应用程序的最终结果就是

ionic cordova run android --prod 但是您可以稍后使用它来发布应用程序。
