I was trying to deploy my angular app, to GitHub-page, while ending up with this long error which I am finding difficult to understand. I tried online but nothing seems to help. Any suggestions/help would be appreciated.

Thanks

Background

Angular version: 6.1.2

Command Used to deploy the app:

npm install -g angular-cli-ghpages

ng build --prod --base-href repository link

Error

    > ERROR in : Type CountryViewComponent in

This happens because you declared CountryViewComponent component in both module app.module and shared module.

For solution you have to remove CountryViewComponent from one module as per your requirements.

if CountryViewComponent is used in multiple time within your angular app than you have to declare this in shared module and shared module is declare in app module.
