¿Qué sucede?

porque hay un complemento de keyboard duplicado en una aplicación que instalé previamente desde cordova.

Solución: quite el complemento del keyboard ejecutando este command

 $ cordova plugin remove ionic-plugin-keyboard 

Noto que estás usando el complemento cordova de keyboard iónico. Asegúrate de tener instalado el complemento ionic-plugin-keyboard . Teníamos un complemento de com.ionic.keyboard más com.ionic.keyboard , por lo que si instala ambos terminaría con símbolos duplicates. Puede eliminar la versión com.ionic.keyboard .
