Redis CLI工作-并非所有NodeJS Redis客户端

问题描述

我已按照本指南进行操作：https://redislabs.com/blog/redis-on-windows-10/安装以下内容：Windows子系统，Ubuntu和Redis Server，一切似乎都可以通过Windows的Ubuntu终端和redis-cli运行。我可以设置并获取值。但是我的NodeJS客户端无法工作/无法连接（仅是第一次？）。
我已经安装了以下NPM Redis客户端：redis（https://www.npmjs.com/package/redis）。

const redis = require("redis");
const client = redis.createClient();
 
client.on("error",function(error) {
  console.error(error);
});
 
client.set("key","value",redis.print);
client.get("key",redis.print);

第一次解决（它可以设置并读取名为“ key”的键）！但是从此以后！！我尝试关闭并打开Ubuntu终端，重新启动Redis服务器等，但似乎无济于事。 redis-cli始终在ubuntu终端上正常工作-只是NodeJS客户端突然不起作用。

我还尝试安装另一个客户端：https://www.npmjs.com/package/ioredis但是问题仍然存在，并且相同。我这样连接此客户端：

const Redis = require("ioredis");
const redis = new Redis({
    port: 6379,// Redis port
    host: "127.0.0.1",// Redis host
    family: 4,// 4 (IPv4) or 6 (IPv6)
    db: 0,});

// ioredis supports all Redis commands:
redis.set("foo","bar"); // returns promise which resolves to string,"OK"

// Or ioredis returns a promise if the last argument isn't a function
redis.get("foo").then(function (result) {
    console.log(result); // Prints "bar"
});

再次，它第一次与第一个Redis客户端一起使用时，我没有设置任何身份验证/凭据...

我尚未更改默认conf文件中的任何一行。
我刚刚尝试安装Ubuntu 20.04（在运行18.04之前），然后再次从头开始安装Redis-但是结果是一样的：Redis cli工作但没有NodeJS客户端（甚至不是第一次）现在）。

它引发异常，并且在我可以捕获到“重新连接”和“连接”事件之后-然后，它一次又一次地循环运行这些步骤。这样看来它可以连接，但之后又有什么断开连接？

6a。我收到此错误消息（NPM：Redis）：

Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:209:20) {
  errno: -4077,code: 'ECONNRESET',syscall: 'read'
}

      at TCP.onStreamRead (internal/stream_base_commons.js:209:20) {
    errno: -4077,syscall: 'read'
  }
}

6b。或者现在我在使用NPM时收到以下错误消息：ioredis：

[ioredis] Unhandled error event: Error: read ECONNRESET
    at TCP.onStreamRead (internal/stream_base_commons.js:209:20)
    at TCP.callbackTrampoline (internal/async_hooks.js:129:14)
