为什么我的 discord 机器人不发送消息？

Question

My discord bot is not sending any messages, when I type +hi , nothing responds. Although, it is sending the message when it's turned on. When I type +hi , nothing happens.

Here is my code.

// - Discord Requires
const Discord = require('discord.js');
const client = new Discord.Client();
const prefix = '+';
// - Imports
const date = require('date-and-time');
const fs = require('fs');
const express = require("express")();
// - Embed
const { MessageEmbed } = require('discord.js');
// - Logo
const logo = './images/logo.png'
// - On Start
client.once('ready', () =>{
  //- Status and Conlole log Message
  client.user.setPresence({activity: {name:"Counting-Days", type:'WATCHING'}, status:'online'})
  .then(console.log)
  .catch(console.error);
  setTimeout(function(){
    console.log("🍉I'm ready, from now on I'm gonna count Christmas Days!:)🍉");
  }, 2000);
  // - Current Date and Time
  const now_date = new Date();
  date.format(now_date, 'YYYY/MM/DD HH:mm:ss');
  date.format(now_date, 'ddd, MMM DD YYYY');
  date.format(now_date, 'hh:mm A [GMT]Z');
  date.format(now_date, 'hh:mm A [GMT]Z', true);
  // - Makes the pattern for time
  const time_pattern = date.compile('hh:mm A');
  const time = date.format(now_date, time_pattern);
  const date_pattern = date.compile('ddd, MMM DD YYYY')
  const date_a = date.format(now_date, date_pattern);
  // - Channel Message => Ready
  client.channels.cache.get('935621866926768159').send(`**🎄Christmas Countdown Bot🎄** is awake |Date: **${date_a}**, Time: **${time}**| and waiting to reply to |${prefix}| commands!✅`)
});

// - Calculates the Days until Christmas (25/12/2022)
const newYears = "25 Dec 2022";

const newYearsDate = new Date(newYears);
const currentDate = new Date();

const totalSeconds = (newYearsDate - currentDate) / 1000;
const days = Math.floor(totalSeconds / 3600 / 24);
const hours = Math.floor(totalSeconds / 3600) % 24;
const mins = Math.floor(totalSeconds / 60) % 60;
const seconds = Math.floor(totalSeconds) % 60;

client.on("message", function (message){
  if (message.content === `${prefix}hi`){
    message.channel.send(`Hey, ${days}`);
  }
})
// -Token
client.login('TOKEN')

I've tried restarting the bot several times but it didn't work. I also tried the code on another bot and it worked.

The problem most likely lies on your message function. Discord.js has replaced the old client.on("message... and replaced it with client.on("messageCreate... .

You've done:

client.on("message", function (message){
  if (message.content === `${prefix}hi`){
    message.channel.send(`Hey, ${days}`);
  }
})

The correct way to do this is as follows:

client.on("messageCreate", function (message) => {
  if(message.content === `${prefix}hi`){
    return message.channel.send(`Hey, ${days}`);
  };
})

It is likely that you've got two bots with different versions of discord.js, the older discord.js@v13 works with the .on("message) and gives a deprecation error in the console while the newer discord.js@v14 completely ignores the .on("message") as it is no longer an event.

Simply delete the incorrect event listener and replace it with the correct one.

It would be better if you had given a discord.js version to help the community understand your problem more.
