我不斷收到類型錯誤：無法讀取未定義的屬性“緩存”

Question

我在 discord.js 中創建了這個不和諧的歡迎器，但我不斷收到此錯誤：

const message = welcome <@${member.id}> to music and chill! please read the ${member.guild.channel.cache.get(ruleschannel).toString()} welcome <@${member.id}> to music and chill! please read the ${member.guild.channel.cache.get(ruleschannel).toString()} ; ^

類型錯誤：無法讀取未定義的屬性“緩存”

這是我的代碼：

module.exports = (client) => {
   const channelid = "865471665168580628";
   client.on("guildMemberAdd", (member) => {
       const serverid = member.guild.id
       const guild = client.guilds.cache.get(serverid.toString());

       console.log("member");
       const ruleschannel = guild.channels.cache.find(channel => channel.name === "rules");

       const message = `welcome <@${member.id}> to music and chill! please read the ${member.guild.channel.cache.get(ruleschannel).toString()}`;

       const channel = member.guild.channels.cache.get(channelid);
       channel.send(message);
   })
}

我閱讀了很多問題和大量答案，但沒有任何幫助，有人可以幫助我嗎？

Answer 1

很可能是打字錯誤

試試${member.guild.channels.cache.get(ruleschannel).toString()} 。 頻道后缺少s ： ${member.guild.channel.cache.get(ruleschannel).toString()}

guild沒有名為channel屬性，而是channels 。 所以它說undefined並且不能調用undefined cache
