此错误告诉您invite未定义。

当find函数在数组中找不到与测试函数匹配的元素时，它将返回undefined。

你需要通过做这样的事情来处理这种情况：

client.on("guildMemberAdd", async member =>{
if(member.guild.id !== id) return;
member.guild.invites.fetch().then(gInvites =>{
const invite = gInvites.find((inv) => newInv.get(inv.code).uses < inv.uses)
if (!invite) {
// invite does not exist
return;
} else {
// an invite matches the testing function
console.log(invite.inviter.tag)
}
}) 
})
