当不应该在 discord.js 命令处理程序中未定义时，无法读取未定义的属性

问题描述

我用一个简单的ping"命令创建了一个小命令处理程序.命令.但是，尝试访问 message.channel 显示未定义.这是为什么呢?

I created a small command handler with a simple "ping" command. However, trying to access message.channel shows up undefined. Why is this?

./index.js

//Discord, fs, prefix, client etc. declarations

client.commands = new Collection()

const files = fs.readdirSync("./commands").filter(file => file.endsWith(".js")

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

client.on("messageCreate", message => {
  const [command, ...args] = message.content.slice(prefix.length).split(/ +/g)
  if (client.commands.has(command) {
    client.commands.get(command).execute(message, client, args)
  }
})

client.login(/*token*/)

./commands/ping.js

module.exports = {
  name: "ping",
  description: "Make me say pong",
  async execute(client, message, args) {
    message.channel.send("Pong!")
  }
}

推荐答案

虽然 Message.channel 可能有效，但 message 不是 Message<的实例/代码>.它实际上是 Client 的一个实例.参数的顺序总是很重要，将它们放在错误的顺序可能会引发 TypeErrors.这里有1个简单的解决方案

client.commands.get(command).execute(client, message, args)
