Node.js 如何检查我的机器人是否可以在discord.js v12中添加角色？

我已经发出了一个warn命令，为提到的用户提供了一个warning角色，但是我遇到了一个问题。有时服务器所有者可能忘记将bot的角色移动到警告角色之上，这将导致bot无法将角色授予用户。我尝试使用role.editable，但即使角色低于bot的角色，它也会返回false。要发出警告的用户的角色也低于bot。这是我的密码：

const { DiscordAPIError } = require("discord.js");
const Discord = require('discord.js');
const fs = require("fs");
const ms = require("ms")
//let warnedRoleList = JSON.parse(fs.readFileSync("./roleIDs/warnedRole.json", "utf-8"));
var mongoPath = '../../mongo.js' //path.join(__dirname, '..', 'mongo.js');
const mongo = require(mongoPath)
const setWarnedSchema = require('../../schemas/setwarned-schema.js')
const mongoose = require('mongoose');
const cache = {}

const moderation = require('../../util/moderation')
const index = require('../../index.js')
//const commands = require("./commands");

module.exports = {

        var warnedRoleID = null
        warnedRoleID = await setup.getWarnedRoles(guildID)

        warnedRoleID = warnedRoleID.toString()

如果（message.member.roles.highest.comparePosition（member.roles.highest）角色层次结构不是确定角色是否可编辑的唯一因素。例如，如果您的机器人没有
MANAGE\u roles
权限，那么无论机器人的最高角色有多高，
Role#editable
仍将返回false

您要做的是首先检查GuildMember是否可管理（通过
GuildMember#可管理
）。如果不可管理，您就不能期望能够向其添加角色。
然后，您要检查您的bot是否具有
MANAGE\u角色
权限。
最后，您要检查所述“警告角色”的位置是否高于bot的最高角色的位置

最后两个步骤应由
Role#editable
内部完成（请参阅）

所以你能做的就是

如果（！member.manageable | | |！warnedRole.editable）返回console.log（“否，无法向该成员添加角色”）
