如何修复Discord.js开发中出现的CLIENT_MISSING_INTENTS错误

问题原因 #

你声明的 const client = new Client({ intents: [...] }) 是完全未被使用的独立变量，你自定义的EconomyClient继承Client类时，构造函数调用super()没有传入任何intents配置，导致父类Client初始化时缺少必填的意图参数，触发报错。

修复方案 #

修改你的client.js代码如下：

const { Client, Intents, Collection } = require('discord.js');
// 删除原来无用的const client = new Client(...)代码行
class EconomyClient extends Client {
constructor() {
    // 给父类构造函数传入intents配置
    super({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] });
    this.discord = require('discord.js');
    this.fs = require('fs');
    this.path = require('path');
    this.ms = require('ms');
    this.mongoose = require('mongoose');
    this.commands = new Collection();
    this.timeouts = new Collection();
    this.config = {
        prefix: 'h!',
    }
}
commandHandler(path) {
    this.fs.readdirSync(this.path.normalize(path)).map((f) => {
        const File = require(this.path.join(__dirname, '..', path, f));
        this.commands.set(File.name, File);
    });
};
start(token, path) {
    this.commandHandler(path);
    this.login(token);
    this.mongoose.connect('mongodb+srv://dbUser:@cluster0.awhb3.mongodb.net/Data?retryWrites=true&w=majority', {
        useNewUrlParser: true,
        useUnifiedTopology: true
    });
    this.mongoose.connection.on('connected', () => console.log("DB connected"));
}
};
module.exports = EconomyClient

额外注意事项 #

• 如果你使用的是discord.js v14及以上版本，intents的写法需要调整为：

const { Client, GatewayIntentBits, Collection } = require('discord.js');
// super里的配置替换为以下内容
super({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.MessageContent] });

• 涉及读取消息内容的功能，需要提前到Discord开发者后台的Bot设置页，开启Message Content Intent权限。
