Question

我已经在一个机器人上工作了12天，我需要升级到v12。一切都进行得很顺利，直到我尝试了一个将给所提到的用户指定角色的命令。

我有2个变量。一个是用户指定的角色变量和成员变量（等于message.guild.members.get（args [0]））。

代码如下：

let Member = message.mentions.members.first() || message.guild.members.get(arguments[0]);
    if (!Member) return message.channel.send("Error: Either the member does not exist or you haven't put the member to give the role to!");
    let role = message.guild.roles.cache.some(r => r.name === arguments[1]) || message.guild.roles.cache.some(r => r.id === arguments[1]) || message.mentions.roles.first();
    if (!role) return nessage.channel.send("Error: Please provide a valid role!");
    
    // if (role === "undefined") {
        // let role = message.guild.roles.cache.some(r => r.name === arguments[1]) || message.guild.roles.cache.some(r => r.id === arguments[1]) || message.mentions.roles.first();
    // }
    
    if (Member.roles.cache.has(role.id)) {
        return message.channel.send("Error: The mentioned user already has that role!");
    } else {
        let role = message.guild.roles.cache.some(r => r.name === arguments[1]) || message.guild.roles.cache.some(r => r.id === arguments[1]) || message.mentions.roles.first();
        console.log(message);
        console.log("role" + role);
        Member.roles.add(role.id).catch(e => console.log("Error: " + e.message));
    }

代码对我来说看起来不错，并希望它能正常工作，但是随后在控制台中出现错误。它没有说未定义什么变量，而只是说它未定义。

我尝试检查角色变量是否未定义，但由于它不起作用而将其注释掉。然后，我让它打印消息并检查角色是否未定义。角色变量很好。消息变量很好。即使是Member变量也可以。

我使用最新的Node.js。

这是控制台日志：

谢谢！

编辑：好像role.id是未定义的。我将尝试看看如何解决该问题。

我认为这部分代码有问题

    console.log("role" + role); // true
    Member.roles.add(role.id).catch(e => console.log("Error: " + e.message));

您尝试在角色中添加undefined，因为：

const roleId = (true).id;
console.log(roleId); //undefined

您从some函数获得了布尔值，该函数始终返回true或false，请尝试将其更改为find

尝试添加一些 id ，例如733951355240316948。

我不知道role.id的样子，但是角色必须是Object

例如：

{
  id:'asdasdawe3534536456',
  // other fields
}

您需要在.add中找到期望的Member.roles.add功能

Node.js捕获了未定义但已定义的错误
