Build error: can't find symbol KeyRegistry

Ionic Framework ionic-v3
1

I have just installed the Ionic Cloud components with:

npm install @ionic/cloud-angular --save

but as soon as I import the libraries with:

import { CloudSettings, CloudModule } from ‘@ionic/cloud-angular’

I get the following error. I did not even setup my cloudSettings or made any use of these libraries. Simply importing them is enough to get the error.

It works fine when I run “ionic serve -c” but I get this error when ever I run “ionic run android” or “ionic build android”.

Any clues?

I got it to work this morning!
Just uninstall and update to all latest versions.

npm uninstall -g ionic
npm install -g ionic@latest
npm uninstall ionic-angular
npm install ionic-angular@latest --save
npm uninstall @ionic/app-scripts
npm install @ionic/app-scripts@latest --save-dev

It then told me that prod.main.ts and dev.main.ts were deprecated and they needed to be deleted and replaced with a simple main.ts. So I just started a new project and copied the main.ts from this new project into my current project and delete the dev/prod files. Just ran a build and it seems to compile fine now! :slight_smile:
