看起来member.guild是undefined，这可能意味着member不是GuildMember对象。在调用run函数(在message事件处理程序内部(时，请检查是否将message.member作为第三个参数传递。修复后，请删除对member.guild的cache调用。Guild对象没有cache属性。由于您使用的是discord.js v11，因此guild.channels返回一个Collection。因此，您可以使用guild.channels.get来获取通道。在v12中将guild.channels的返回类型更改为GuildChannelManager。

// discord.js v11
member.guild.channels.get('820470375602847745')
// v12
member.guild.channels.cache.get('820470375602847745')

您也可以在v11中使用message.guild.channels来访问通道集合。

// discord.js v11
message.guild.channels.get('820470375602847745')
// v12
message.guild.channels.cache.get('820470375602847745')
