TypeError: member.roles.add is not a function (discord.js v13)

Question

我正在开发一个机器人，它需要在 giving/removing 来自用户的角色之前检查一些事情，但由于某种原因，.has()、.some()、.add() 和 .remove() 函数不起作用。

这是我的代码：

const Permissions = require('discord.js');

function isAdmin(member) {
    return member.permissions.has(Permissions.FLAGS.ADMINISTRATOR);
}

function hasRole(member, roleID) {
    return member.roles.some(role => role.id === roleID);
}

function giveRole(member, role) {
    member.roles.add(role)
}

function removeRole(member, role) {
    member.roles.remove(role);
}

这是我得到的完整错误：

Answer 1

在对角色进行任何操作时，以及大多数一般情况下，您需要通过 cache 访问它，例如：

  function hasRole(member, roleID) {
      return member.roles.cache.some(role => role.id === roleID);
  }

Answer 2

在 Discord.js 版本 12 中，语法大部分发生了变化。缓存属性现在包含了很多角色的缓存，你有可能需要使用 Promise 并获取它...

// in an ASYNC FUNCTION
let roles = await member.roles.fetch();
return roles.some(role => role.id === roleID);

Answer 3

你试过这样吗？

var role = message.guild.roles.cache.find(role => role.name === "Role_Name")
member.roles.add(role)

var role = message.guild.roles.cache.find(role => role.id === "Role_Id")
member.roles.add(role)

Answer 4

看了 Discord.js class 之后，我发现你不能简单地使用

let member = interaction.member;

获得公会成员，但是，你必须做

let member = await guild.members.fetch("ID");

这样做之后，member.permissions.has、member.roles.add 和 member.roles.remove 功能都可以使用了！

唯一仍然不起作用的函数是member.roles.some，这是因为GuildMemberRoleManagerclass只有add，set，和 remove 函数。 member.roles.some 函数可以更改为使用 member._roles，因为它 returns 包含公会成员拥有的所有角色的字符串列表，并且可以这样做：

function hasRole(member, roleID) {
    return member._roles.indexOf(roleID) >= 0;
}
