Topic: Error: NG0300: Multiple components match node with tagname mat-spinner"

jbull priority asked 3 years ago

Expected behavior My application loads the main screen without error

Actual behavior When my application loads I get an error "Error: NG0300: Multiple components match node with tagname mat-spinner"

This problem started when I installed ng-uikit-pro-standard. My import in the app.module is import { MDBBootstrapModulesPro } from 'ng-uikit-pro-standard';

and then in @NgModule imports section I have MDBBootstrapModulesPro.forRoot()

I found that by removing an import to MatProgressSpinnerModule that the error goes away. Can MDB and Material UI live together in a project? It seems that there is a naming collision somewhere.

@jbull We will take a closer look at that and let you know what we found. There is a possibility that this problem is caused by a naming collision.
