Discord Bot无法上线，调用client.login()报AbortController未定义错误

相关代码 #

require("dotenv").config();
const { Client, Intents } = require("discord.js");

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

client.on("ready", () => {
  console.log("bot is ready");
});

client.login(process.env.DISCORD_BOT_TOKEN).catch((e) => {
  console.log(e);
});

排查过程 #

• 报错由client.login()方法触发
• 已三次核对机器人token，确认token正确
• 排除环境变量读取问题，直接传入token依然无法运行

根因与解决方法 #

• 根因：Node.js运行环境版本过低，discord.js库最低要求v16版本的Node.js运行环境，AbortController是高版本Node.js才内置的全局API，低版本环境不存在该变量因此触发引用错误。
• 解决方法：将本地Node.js版本升级至v16或更高版本即可解决该问题。
