角度-如何修复“属性不存在类型”错误？

Question

我正在遵循这个视频教程（文本版本相同）。我遵循了完全相同的代码，并收到了以下错误：

错误TS2339:属性“Get Employees”在类型“EmployeeService”上不存在

//import statements go here ...

@Injectable()
export class EmployeeService {
private listEmployees: Employee[] = [
    {
      //just to avoid longer code, deleted dummy data.
    },
  ];

  getEmployees(): Employee[] {
      return this.listEmployees; //ERROR in src/app/employees/list-employees.component.ts(14,44)
  }
}

//import statements
@Component({
    selector: 'app-list-employees',
    templateUrl: './list-employees.component.html',
    styleUrls: ['./list-employees.component.css']
})
export class ListEmployeesComponent implements OnInit {
    employees: Employee[];
    constructor(private _EmployeeService: EmployeeService) { }

    ngOnInit() {
        this.employees = this._EmployeeService.getEmployees();
    }

}
