I've seen a lot of questions on this but doesn't seem to be the same issue Im encountering. I have just created my 2nd angular project. I have a new component under src/app/employees where I am trying to use in employees.component.html . The error I am getting is:

Uncaught Error: Template parse errors:
'mat-card' is not a known element:
1. If 'mat-card' is an Angular component, then verify that it is part of this module.
2. If 'mat-card' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message. ("[ERROR ->]<mat-card> </mat-card>

Now, in app.module.ts I have:

import BrowserModule from "@angular/platform-browser";
import BrowserAnimationsModule from "@angular/platform-browser/animations";
import LOCALE_ID, NgModule from "@angular/core";
import HttpClientModule, HTTP_INTERCEPTORS from "@angular/common/http";
import AppRoutingModule from "./app-routing.module";
import AppComponent from "./app.component";
import 
 MatButtonModule,
 MatFormFieldModule,
 MatIconModule,
 MatInputModule,
 MatListModule,
 MatSelectModule,
 MatSidenavModule,
 MatCardModule,
 MatTableModule
 from "@angular/material";

@NgModule(
 declarations: [AppComponent],
 imports: [
 BrowserModule,
 BrowserAnimationsModule,
 AppRoutingModule,
 HttpClientModule,
 MatButtonModule,
 MatFormFieldModule,
 MatIconModule,
 MatListModule,
 MatInputModule,
 MatSelectModule,
 MatSidenavModule,
 MatCardModule,
 MatTableModule
 ],....
)
export class AppModule 

And there aren't any errors if I use mat-card in app.component.html.
What am I missing here?

I can not see your EmployeesComponent in your list of declarations. The EmployeesComponent need to be declared in the same module as where you import the MatCardModule, like:

declarations: [
 EmployeesComponent
],
imports: [
 MatCardModule
]

I am guessing either that you have forgotten to declare the EmployeesComponent in your app module, or that you have another module, perhaps Employees module, where you have to import the MatCardModule.
