I started getting "export was not found in '@angular/core' " after uninstalling then reinstalling a package

Question

I have a project which was working perfectly except for some minor error when using @nebular and angular material's dialog and pagination so I thought I might fix it if i uninstall then reinstall those packages but I got an even worse error and my project doesn't work anymore.

I even tried updating typescript and uninstalling those packages but i'm still getting this error

Here's the error:

Solution

"@angular/cdk": "^8.0.0", should be changed to a version matching the version of angular you are running.

Should be ^6.x.x or ^7.x.x

I think ^8.x.x only works with angular 8.

Thank you! Would have taken forever to figure that out!!
