I also faced same issue and this worked for me.
Use this version of coreui – “@coreui/angular”: “2.5.3”
Look like the QueryParamsHandling is not referred in this version as per code of this version.
Also if you have already run npm install then you need to remove it manually then add it again with version 2.5.3 and make sure you have mentioned exact version in your package.json (without cart or tilde symbol).
Changing @coreui/angular version didn’t work for me,
but changing import statement in the
[email protected]file to :will immediately work.
I managed to solve it like this. Go to @ angular / router / router "and insert the word ‘export’ before the QueryParamsHandling declaration:
export declare type QueryParamsHandling = ‘merge’ | ‘preserve’ | ”;
