discord.js - 启动时弹出错误消息：“提供了错误的登录详细信息”

我正在遵循指南。我遇到node index.js了Windows PowerShell，但没有提供预期的输出

它是从discord.js指南中复制并粘贴的。我已经运行了很多次，每次都有相同的确切错误。

// require the discord.js module
const Discord = require('discord.js');

// create a new Discord client
const client = new Discord.Client();

// when the client is ready, run this code
// this event will only trigger one time after logging in
client.once('ready', () => {
console.log('Ready!');
});

// login to Discord with your app's token
client.login('your-token-goes-here');

expected: Ready!
actual:
