@ nestjs / websockets与Guards一起使用host.setType失败

Question

我正在尝试将JWT身份验证添加到nestJs WebSockets。
我可以从客户端连接并发送标头。
但是，在使用防护设置nestJs WebSocket时出现错误TypeError: host.setType is not a function。

错误源自ws-proxy.js ExecutionContextHost的返回值没有名为setType的属性/方法，但在第27行：已使用

我的Guard.ts文件如下。

import { CanActivate, ExecutionContext, Injectable } from '@nestjs/common';
import * as configs from 'config';
import { Socket } from 'socket.io';
import { JwtService } from '@nestjs/jwt';
import { JwtPayload } from '../jwt-payload.interface';
import { WsException } from '@nestjs/websockets';

@Injectable()
export class JwtGuard implements CanActivate {
  constructor(private readonly jwtService: JwtService) { }

  async canActivate(context: ExecutionContext): Promise<boolean> {

    try {
      const client: Socket = context.switchToWs().getClient<Socket>();
      const authHeader: string = client.handshake.headers.authorization;
      const authToken = authHeader.substring(7, authHeader.length);
      const jwtPayload: JwtPayload = await this.jwtService.verifyAsync(authToken, configs.get('JWT.publicKey'));
      const user: any = this.validateUser(jwtPayload);

      context.switchToWs().getData().user = user;
      return Boolean(user);
    } catch (err) {
      throw new WsException(err.message);
    }
  }

  validateUser(payload: JwtPayload): any {
    return payload;
  }
}

套接字文件是

import { SubscribeMessage, WebSocketGateway } from '@nestjs/websockets';
import { Socket } from 'socket.io';
import { UseGuards} from '@nestjs/common';
import { JwtGuard } from '../../../common/authentication/jwt-guard/jwt.guard';

@UseGuards(JwtGuard)
@WebSocketGateway()
export class ContractGateway {
  @SubscribeMessage('message')
  handleMessage(client: Socket, payload: any): Boolean {
    return true;
  }
}

有人遇到这种错误以及如何解决吗？

发现了问题，"@nestjs/websockets": "^6.8.2"和"@nestjs/core": "^6.0.0",之间的程序包冲突。我需要升级所有@nestjs软件包
