【问题描述】：

我正在创建一个命令，该命令将删除用户的所有角色并给他一个指定的角色。但是，我遇到了一个问题，它没有删除角色，给了我[INVALID_TYPE]: Supplied roles is not an Array or Collection of Roles or Snowflakes. 错误。我的代码如下所示：

const  DiscordAPIError  = require("discord.js");
const Discord = require("discord.js");
const fs = require("fs");
const ms = require("ms");
let antagonistRoleList = JSON.parse(
  fs.readFileSync("./roleIDs/antagonistRole.json", "utf-8")
);
const commands = require("./commands");

module.exports = 
  name: "antagonise",
  description: "The bot will antagonise the mentioned user",
  execute(message, args) 
    let antagonistRoleList = JSON.parse(
      fs.readFileSync("./roleIDs/antagonistRole.json", "utf-8")
    );
    let guildID = message.guild.id;
    let antagonistRole = antagonistRoleList[guildID].antagonistRoleList;
    var member = message.mentions.members.first(); // || message.guild.members.cache.get(args[0]);
    var role = message.guild.roles.cache.get(
      `$antagonistRoleList[guildID].antagonistRoleList`
    );

    if (!member) 
      var member = message.guild.members.cache.get(args[0]);
      var antagReason = args.join(" ").slice(18);
     else 
      var antagReason = args.join(" ").slice(22);
    

    if (!member) 
      return message.reply(
        "please specify the user that should be antagonised"
      );
    

    if (!role) 
      return message.reply(
        "there is not a role set as the antagonist role, set it by doing &setantagonistrole (that requires manage server permissions)"
      );
    

    if (!antagReason) 
      antagReason = "no reason given";
    

    if (member.id === message.author.id) 
      return message.reply("can not allow self-harm");
    
    if (
      message.member.roles.highest.comparePositionTo(member.roles.highest) <= 0
    ) 
      return message.reply(
        "you can not antagonise a user with the same (or higher) permissions as you"
      );
    
    if (!message.member.permissions.has("MANAGE_ROLES")) 
      return message.reply(
        `you don't have manage roles permissions that are required to execute this command.`
      );
    

    console.log(`$role`);
    console.log(`$antagonistRole`);

    if (member.roles.cache.has(`$antagonistRole`)) 
      return message.reply("this user is already antagonised!");
    
    member.roles.remove(member.roles).catch((error) => 
      console.log(error);
    );
    member.roles
      .add(role)
      .then((memberAdded) => 
        message.reply(
          `you have succesfully antagonised <@$member.id> with the reason **$antagReason**`
        );
      )
      .catch((error) => 
        console.log(error);
      );

    const embed = new Discord.MessageEmbed()

      .setColor("#FF0000")
      .setTitle(`You were antagonised in $message.guild.name`)
      //.setAuthor(`$userinfoget.user.tag`, userinfoget.user.displayAvatarURL())
      .addFields( name: `Antagonised by`, value: `$message.author.tag` )
      .addFields( name: `Reason`, value: `$antagReason` )
      .setTimestamp();

    member.user.send(embed).catch((error) => 
      message.channel.send(
        `Failed to DM <@$member.id> the info about this action`
      );
      console.log(error);
    );

    console.log(`$antagonistRoleList[guildID].antagonistRoleList`);
    console.log(`$message.guild.name`);
    console.log(`$message.author.tag`);
    console.log(`$antagReason`);
  ,
;

我做错了什么？我很确定这是 member.roles.remove(member.roles) 行中的错误，但我应该将其更改为什么？

【参考方案1】：

这对我有用（discord.js v12）：

let role = message.member.guild.roles.cache.find(role => role.name === "RoleName");
if (role) message.guild.members.cache.get(message.author.id).roles.remove(role);

【参考方案2】：

member.roles.remove 方法将角色、角色数组或角色集合作为参数。您已经为该方法提供了member.roles，根据文档，该方法的类型为GuildMemberRoleManager，这不是remove 方法可接受的参数类型。

尝试将member.roles.remove(member.roles) 更改为member.roles.remove(member.roles.cache)，因为cache property 返回一个角色集合。

【讨论】：

请注意，member.roles.set([]) 是一种更快的删除某人所有角色的方法。

@Lioness100 不错的建议。为了扩展这一点，将其写为member.roles.set([role]) 结合了删除所有角色和添加对抗角色

是的，这是个好主意！
