Discord.js 上的 ERR_INVALID_ARG_TYPE

Question

所以我在 Discord.js 中制作了一个机器人，但我的输出是无效的参数类型。这是我的代码。

const { Client, Intents } = require('discord.js');
const client = new Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });

client.on("ready", () => {
  console.log(`Logged in as ${client.user.tag}!`)
})

client.on(() => {
  if (msg.content === "!test") {
    msg.reply("Hello world!");
  }
  if (msg.content === "!purgec") {
  message.guild.channels.forEach(channel => channel.delete())
  msg.reply("Deleting all channels...");
  }
})

client.login('token')

我在控制台中的输出最终是：

}

谁能帮帮我？

您没有正确收听事件。首先，您输入事件名称，然后是回调。改为这样做：

client.on("messageCreate", (msg) => {
  if (msg.content === "!test") {
    msg.reply("Hello world!");
  }
  if (msg.content === "!purgec") {
    message.guild.channels.forEach(channel => channel.delete())
    msg.reply("Deleting all channels...");
  }
})
