Typescript-找不到命令工厂的类型

Question

我刚问过can not find type the return value of a class factory function，提供的方法在我的抽象中起作用，但是当我在实际代码中实现该方法时，我仍然遇到类型错误，我想修复IParticipantCommands以输出正确的类型，但是我尝试的所有事情都会给我带来错误

interface IParticipantCommands {
  AddParticipantCommand:  new (s: INewParticipantDTO) => INexusCommand<INewParticipantDTO>;
}

export function participantCommandFactory(args: IParticipantCommandFactoryArgs): IParticipantCommands {
  const ParticipantCommand = moduleCommandFactory(args);

  class AddParticipantCommand extends ParticipantCommand<INewParticipantDTO> {
    public getType(): CommandType<string, string> {
      return {
        subject: ParticipantCommandSubject.PARTICIPANT,
        verb: ParticipantCommandVerb.ADD,
      };
    }
  }
  return {
    AddParticipantCommand,
  };
}

以上代码中使用的其他接口和功能

export interface INexusCommand<T> extends ICommand, Command<T, string, string> {
  readonly type: CommandType<string, string>;
}

export function moduleCommandFactory({ domain, module }: CommandFactoryArgs) {
  return class Command<T> implements INexusCommand<T> {
    public readonly body: T;
    public readonly type: CommandType<string, string>;
    public readonly header: CommandHeader & { uuid: UUID }; // Don't type uuid as UUID | null

    constructor(body: T, user: ModuleObject, organization: ModuleObject) {
      this.type = this.getType();

      this.body = body;

      this.header = {
        timestamp: Date.now(),
        uuid: uuid.v4(),
        saga: uuid.v4(),
        domain,
        module,
        organization,
        user,
      };
    }

    getType(): CommandType<string, string> {
      throw new Error('Command must specify getType() function');
    }
  };
}

export interface INewParticipantDTO extends Omit<IParticipant, 'id'> {}
 export interface IParticipant extends IModuleLink {
  id: UUID;
  /**
   * what is there "job" related to the module ( What they should do ) and can be defined on a per module basis
   * Note: this does not have any relationship to what they are Allowed/Authorized to do, someone could be a "Manager" and not have any ability to edit or view anything
   */
  roles: string[];
  /**
   * what are they authorized to do
   */
  scopes: TParticipantScope[];
  /**
   * Last time this participant interacted with they module
   */
  last_interaction: ISODATE | null;
}
