【问题描述】：

因此，即使用户应该做出反应，我的机器人也不会发送消息，然后出现错误...顺便说一句，由于 promise 拒绝错误，我在代码中放了很多 .catch 错误

client.on("guildMemberAdd", member => 
    try 
        member.send(`Hello $member, welcome to the PotatoHost Server! 
I want to help you and so my question is: Do you want to buy a server or do you need more informations first? \n
A: I want to buy a server
B: I need more informations first \n
Please react to this message with A or B.`)
        .catch(err => console.log('err1'))
        .then(function (message) 
            message.react("????")
            .catch(err => console.log(err));
            message.react("????")
            .catch(err => console.log(err));
            message.awaitReactions((reaction, user) => user.id == message.author.id && (reaction.emoji.name == '????' || reaction.emoji.name == '????'),
                 max: 1)
                .catch(err => console.log(err))
                .then(collected => 
                    if (collected.first().emoji.name == '????') 
                        message.send('Ok, so you want to buy a server. Let me recommend you to visit <#699374469977735208>.')
                        .catch(err => console.log(err));
                    
                    else
                      message.send('Ok, so you need more informations first. Let me recommend you to visit <#699374469977735208>.')
                      .catch(err => console.log(err));
                )
        );
    catch (err) 
         console.log(err)
    
)

以下是我不知道如何解决的错误：

(node:31944) UnhandledPromiseRejectionWarning: TypeError: message.send is not a function
    at C:\Users\nicos\OneDrive\Documents\Discord Bots\PotatoHost Bot\index.js:27:33

【参考方案1】：

没有 message.send() 这样的东西，你需要用 message.channel.send() 替换它
