无法读取未定义(Discord.js)的属性'send‘

Question

抱歉打扰你们了。我写了一段代码，但我认为这段代码有问题，因为我是js和discord.js的新手。感谢任何人的帮助(我也看了一些其他问题，但我找不到像我这样的例子)

const Discord = require('discord.js');
module.exports = {
    name: "ping",
    description: "Returns latency and API ping",
    execute: 
    async (client, message, args) => 
    {
        try
        {
        const msg = await message.channel.send(`? Pinging....`);

        msg.edit(`? Pong!
        latency ${Math.floor(msg.createdTimestap - message.createdTimestap)}ms
        API latency ${Math.round(client.ping)}ms`);
        }catch(e){console.log(e)}```

    }
}

这里是控制台：

正如评论者所指出的那样，在函数中接收的消息没有通道属性。

您可以调试应用程序并查看参数在执行时的值，也可以对它们执行console.log()并对其进行测试，以便更好地了解正在发生的事情。

如果你正在遵循Discord.js文档中的指南，你可能想看看这个repository，它展示了一个动态执行命令的工作示例。

出于stackoverflow的目的，我将该代码库中的相关代码粘贴到下面：

index.js

const fs = require('fs');
const Discord = require('discord.js');
const { prefix, token } = require('./config.json');

const client = new Discord.Client();
client.commands = new Discord.Collection();

const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));

for (const file of commandFiles) {
    const command = require(`./commands/${file}`);
    client.commands.set(command.name, command);
}

client.once('ready', () => {
    console.log('Ready!');
});

client.on('message', message => {
    if (!message.content.startsWith(prefix) || message.author.bot) return;

    const args = message.content.slice(prefix.length).trim().split(/ +/);
    const command = args.shift().toLowerCase();

    if (!client.commands.has(command)) return;

    try {
        client.commands.get(command).execute(message, args);
    } catch (error) {
        console.error(error);
        message.reply('there was an error trying to execute that command!');
    }
});

commands/ping.js

module.exports = {
    name: 'ping',
    description: 'Ping!',
    execute(message) {
        message.channel.send('Pong.');
    }

config.json

{
    "prefix": "!",
    "token": "your-token-goes-here"
}
