Angular error - Generic type 'ModuleWithProviders' requires 1 type argument(s)

Question

After upgrading from Angular version 8 to 10.

Running the - ng serve command gives me error -

ERROR in node_modules/ngx-tree-select/src/module.d.ts:11:56 - err

Answer 1

To skip this type error just add in you code:

declare module "@angular/core" {
    interface ModuleWithProviders {
        ngModule: Type;
        providers?: Provider[];
    }
}

Note: this will fix the type checking and allow to continue - if you will notice other lib to Angular10 inconmpatibilities - you need to ask lib upgrade or found another one.
