【问题描述】：

我制作 discord 机器人已经有一段时间了，最近我为它添加了一个 kick 功能，但是每当我对角色比机器人更高的人使用该命令时，机器人就会自动关闭。我正在使用不和谐 v12.22.1

这是我的代码

    const { member, mentions } = message

    const tag = `<@${member.id}>`

    if (
      member.hasPermission('KICK_MEMBERS')
    ) {
      const target = mentions.users.first()
      if (target) {
        const targetMember = message.guild.members.cache.get(target.id)
        targetMember.kick()
        const embed = new Discord.MessageEmbed()
        .setColor('RANDOM')
      .setDescription(`that user has been KICKED`);
    message.channel.send(embed);
      } else {
        message.channel.send(`${tag} Please specify someone to kick.`)
      }
    } else {
      message.channel.send(
        `${tag} You do not have permission to use this command.`
      )
    }
  })
})

它给了我这个错误：

(node:339) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:339) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

【问题讨论】：

您收到任何错误吗？您使用的是 discord.js v12 还是 v13？我们需要更多细节。
是的，它给出了这个很长的错误，：s/discord.js/src/rest/RequestHandler.js:39:14) (node:339) UnhandledPromiseRejectionWarning：未处理的承诺拒绝。此错误源于在没有 catch 块的情况下抛出异步函数内部，或拒绝未使用 .catch() 处理的承诺。我也在使用不和谐 v12.22.1
能否将错误添加到问题中，以便读者真正阅读和理解错误？
好吧，我做到了，现在你知道我该如何解决这个问题了

【解决方案1】：

Discord.js 为您的问题提供了一个简单的解决方案。任何公会成员都有一个 member.kickable 属性，如果你能踢他们就为真，如果你不能踢他们就为假。

这可以添加到您的代码中：

if (!targetMember.kickable) {
    return message.channel.send("I cannot kick that user!")
}

您的最终代码将类似于

const { member, mentions } = message;
const tag = `<@${member.id}>`;

if(member.hasPermission('KICK_MEMBERS')) {
    const target = mentions.users.first();
    if(target) {
        const targetMember = message.guild.members.cache.get(target.id);

        if(!targetMember.kickable) {
            return message.channel.send("I cannot kick that user!");
        }

        targetMember.kick();
        const embed = new Discord.MessageEmbed()
        .setColor('RANDOM')
        .setDescription(`that user has been KICKED`);
        message.channel.send(embed);

    }else{
        message.channel.send(`${tag} Please specify someone to kick.`)
    }
}else{
    message.channel.send(`${tag} You do not have permission to use this command.`);
}

【解决方案2】：

一个简单的解决方案是使用<member>.kick(...).catch(...) 来捕获<member>.kick(...) 可能向您抛出的任何错误。

例子：

const member = await (client.guilds.fetch(message.guild.id)).members.cache.get(message.author.id); // Get the member

if (member.hasPermission('KICK_MEMBERS')) { // Make sure the user had permission to kick members
    const target = message.mentions.users.first(); // Get the user to kick
    if (target) { // If the target exists
        const targetMember = message.guild.members.cache.get(target.id); // Get the targets guild member data
        targetMember.kick({ reason: 'enter-reason-here' }).catch(() => message.channel.send('I don\'t have permissions to kick ' + target.id); // Kick a member and if failed, tell the user that executed the command
    }
}

完整示例：

const member = await (client.guilds.fetch(message.guild.id)).members.cache.get(message.author.id); // Get the member
const tag = `<@${member.user.id}>`; // Get the members user ID

if (member.hasPermission('KICK_MEMBERS')) { // Make sure the user had permission to kick members
    const target = message.mentions.users.first(); // Get the user to kick
    if (target) { // If the target exists
        const targetMember = message.guild.members.cache.get(target.id); // Get the targets guild member data
        targetMember.kick({ reason: 'enter-reason-here' }).catch(() => message.channel.send('I don\'t have permissions to kick ' + target.id); // Kick a member and if failed, tell the user that executed the command
        const embed = new Discord.MessageEmbed()
          .setColor('RANDOM')
          .setDescription(`that user has been KICKED`);
        message.channel.send(embed); // Send the success embed
    } else
        message.channel.send(`${tag} Please specify someone to kick.`); // If the user didn't mention a user to kick
} else
    message.channel.send(`${tag} You do not have permission to use this command.`); // Tell the member they don't have permission to use the command
