【问题描述】：

我想在用户向任何文本频道发送消息时赋予角色。但我在某处犯了错误。

const Discord = require('discord.js');
const client = new Discord.Client();
const config = require('./config.json');

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

client.on("message", msg => {
  var sender = msg.author;
  var message= msg.content;
  const guild = client.guilds.cache.get("847874027149721680");

  let role = message.guilds.roles.cache.find("848033734909231156");
  if (message) {
    message.author.addRole(role).catch(console.error);
  }
});
client.login(process.env.DISCORD_TOKEN);

我经常收到这个错误

/home/runner/Project/index.js:23
  let role = message.guilds.roles.cache.find("848033734909231156");
                            ^

    at WebSocket.emit (events.js:314:20)

我是新手，所以我可能很笨。对不起

标签： discord.js

【解决方案1】：

这是message.guild.roles.cache.get()，而不是message.guilds.roles.cache.get()。

【讨论】：

问题依旧
TypeError: 无法读取未定义的属性“角色”
啊，好的。尝试将message.guild 替换为client.guilds.cache.get(message.guild.id)。

【解决方案2】：

正如 japanballdev 所指出的，您犯了拼写错误。修复后它仍然存在的原因是因为您在两个地方犯了这个错误：

client.on("message", msg => {
  var sender = msg.author;
  var message= msg.content;
  const guild = client.guild.cache.get("847874027149721680"); //ERROR WAS HERE

  let role = message.guild.roles.cache.find("848033734909231156"); //ERROR WAS HERE TOO
  if (message) {
    message.author.addRole(role).catch(console.error);
  }
});
