有人知道如何解决错误，因为idk，我尝试了几件事，但没有任何效果。我是初学者。
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.`)
.then(function (message) {
message.react("?")
message.react("?")
message.awaitReactions((reaction, user) => user.id == message.author.id && (reaction.emoji.name == '?' || reaction.emoji.name == '?'),
{ max: 1}).then(collected => {
if (collected.first().emoji.name == '?') {
message.send.catch(err => console.log(err))('Ok, so you want to buy a server. Let me recommend you to visit <#699374469977735208>.');
client.destroy();
}
else
message.send.catch(err => console.log(err))('Ok, so you need more informations first. Let me recommend you to visit <#699374469977735208>.');
})
});
}catch (err) {
console.log(err)
}
})
