channel.join()不是函数！有谁可以帮我？Discord.js

const { Client } = require('discord.js');
const client = new Client();

client.on('message', async (message) => {
  if (message.content === '!join') {
    if (message.member.voice.channel) {
      try {
        const connection = await message.member.voice.channel.join();
        console.log('Bot joined the voice channel');
      } catch (error) {
        console.error('Error joining the voice channel:', error);
      }
    } else {
      message.reply('You need to be in a voice channel to use this command!');
    }
  }
});

client.login('YOUR_BOT_TOKEN');
