discord.js开发报错：TypeError: REST is not a constructor 求助

问题原因 #

你遇到的错误是因为Discord.js v13及以上版本中，REST模块被拆分到了独立的@discordjs/rest包中，不再包含在discord.js核心包内。直接从discord.js导入REST会导致获取到的不是构造函数，从而抛出该错误。

解决方案 #

1. 安装独立的REST包 #

在项目根目录执行以下命令：

npm install @discordjs/rest

2. 修改代码中的导入语句 #

将原来的：

const { REST, Routes } = require('discord.js');

替换为：

const { REST } = require('@discordjs/rest');
const { Routes } = require('discord.js');

3. 版本适配（可选） #

如果你的discord.js版本低于v13，建议升级到稳定的v13/v14版本以避免更多兼容性问题：

npm install discord.js@latest

修改后的完整代码示例：

const config = require("./config.json");
const Discord = require('discord.js');
const { Intents } = Discord;
const client = new Discord.Client({ 
  intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES] 
})
const { REST } = require('@discordjs/rest');
const { Routes } = require('discord.js');
const commands = [
  {
    name: 'test',
    description: 'test',
  },
];
const rest = new REST({ version: '10' }).setToken(config.BOT_TOKEN);
(async () => {
  try {
    console.log('Started refreshing application (/) commands.');

    await rest.put(Routes.applicationCommands(config.CLIENT_ID), { body: commands });

    console.log('Successfully reloaded application (/) commands.');
  } catch (error) {
    console.error(error);
  }
})();
client.on('interactionCreate', async interaction => {
  if (!interaction.isChatInputCommand()) return;

  if (interaction.commandName === 'test') {
    await interaction.reply('Hello boi!');
  }
});
client.login(config.BOT_TOKEN)
