I updated from angular 4.4.6 and material beta 19 to angular 5 and material 5.0.0-rc0
The application compiles correctly, but executing on Chrome I get
"Uncaught Error: Unexpected value 'MatTable DataSource' imported by the module 'Material Modules'. Please add a @NgModule annotation."
Other material components work correctly, mat-icon, mat-card-content, mat-tab-group, mat-dialog-xxx ...
Could you help me?
Import the module and enter it in your @NgModule Imports section. This is probably in your something.module.ts.
I had similar issue after upgrading to Angular 5, updating all the dependency like typescript, corejs , angular-cli etc to latest version solved the problem.
MatTableDataSource is in the master branch but it isn't added to the current version.
I hope this link can help you to make your own data source with the Abstract class "DataSource" in the module "@angular/cdk/collections"
