I have switched to different cordova plugin, since this one (cordova-plugin-mobile-ocr) just didn't work.
Any advance on this issue? I'm also dealing with the same problem.
I can't run 'pod install' because PGB (cloud) doesn't support hooks.
Well, there's no solution to the original problem.
I've switched to different plugin entirely, the cordova-plugin-ml-text. That one has a separate dependency, cordova-plugin-firebase, which I've forked and manually updated plist and json auth files from firebase.
Otherwise, no solution to this problem until PhoneGap cloud builds start supporting hooks. :/
