Question

我运行了这段代码

bot.on("presenceUpdate", (oldMember, newMember) => {
    let guildChannels = newMember.guild.channels;
    if(oldMember.status !== newMember.status){
        console.log(`${newMember.user.username} is now ${newMember.presence.status}`);
                guildChannels.find('name','test')
                .send(`${newMember.user.username} is now ${newMember.presence.status}`)
    }
});

在运行此代码段（假设要登录控制台以及将消息发送到“测试”频道）时，会出现以下错误：

TypeError：无法读取未定义的属性“状态”

此行中的错误

    if(oldMember.status !== newMember.status){

这是完整的错误日志

首先全部使用newPresence和oldPresence 第二。它的NewPresence.activities获取更新活动的数组。所以你的鳕鱼看起来像

bot.on("presenceUpdate", (oldPresence, newPresence) => {
    let guildChannels = newMember.guild.channels;
    if(oldPresence.activities !== newMember.activities){
        console.log(`I dont know what u are trying to do.. You can try to get the the stuffs from the array by doing ${newPresence.activities[0].<PROPERTY>}`);
                guildChannels.find('name','test')
                .send(`${newPresence.username} is now ${newPresence.activities[0].<PROPERTY>}`)
    }```
});

discordjs错误：TypeError：无法读取未定义的属性“状态”
