    Re-running this command with the --verbose flag may provide more information.

这是离子信息

离子：

   ionic (Ionic CLI)  : 4.12.0 (I:\ionic\node_modules\ionic)
   Ionic Framework    : ionic-angular 3.9.5
   @ionic/app-scripts : 3.2.2

科尔多瓦：

 cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
   Cordova Platforms     : android 6.4.0, ios 4.5.5
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 4.0.1, (and 4 other plugins)
