I am trying to migrate an ionic 3 app to ionic 4. The problem is that when bringing the components folder from the v3 project to the v4 project, the html templates of these components give an error style:
'ion-header' is not a known element:
'ion-toolbar' is not a known element:
Commenting out the Events import in the component's ts file stops showing the error in the html, but this moves the error to the ts
tried these solutions but none worked for me https://gist.github.com/sagrawal31/76c089251008ac746fc8cf3aef4bc261 https://forum.ionicframework.com/t/the-events-provider-is-deprecated-ionic-4/174160/ 10
