Issue while adding plugin

[demonVibe]

Following the installation instruction for ionic project, I'm getting this error
Command Run> cordova plugin add cordova-plugin-live-ocr --save
Response: (node:6255) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): CordovaError: Invalid Plugin! cordova-plugin-live-ocr needs a valid package.json

This package seems to be missing package.json. Cordova 8.0.0+ requires package.json for installation. @DavidStrausz is it possible for you to update this repo soon?
Thanks!!
