我正在使用nest7.1.5和ioredis4.17.3。我正在尝试创建一个redisservice，然后注入它。到目前为止，我掌握的情况如下：
redis.providers.ts

import { Provider } from '@nestjs/common';
import Redis from 'ioredis';
import { REDIS_CLIENT } from './redis.constants';

export type RedisClient = Redis.Redis;

export const redisProviders: Provider[] = [
    {
        useFactory: (): RedisClient => {
            return new Redis({
                host: 'localhost',
                port: 6379,
            });
        },
        provide: REDIS_CLIENT,
    }
]

redis.service.ts

import { Injectable, Inject } from '@nestjs/common';

import { REDIS_CLIENT } from './redis.constants';
import { RedisClient } from './redis.providers';

@Injectable()
export class RedisService {
    public constructor(
        @Inject(REDIS_CLIENT)
        private readonly redisClient: RedisClient,
    ) { }
}

redis.module.ts

import { Module } from '@nestjs/common';
import { redisProviders } from './redis.providers';
import { RedisService } from './redis.service';

@Module({
    providers: [...redisProviders, RedisService],
    exports: [...redisProviders, RedisService],
})
export class RedisModule { }

当我尝试注入此服务时，出现以下错误：

[12:25:57 PM] Found 0 errors. Watching for file changes.

        __metadata("design:paramtypes", [typeof (_a = typeof redis_providers_1.RedisClient !== "undefined" && redis_providers_1.RedisClient) === "function" ? _a : Object])
                                                             ^

我错过了什么？任何帮助或想法都将不胜感激。谢谢您。
