Question

我开始构建Discord机器人，我做的第一个功能是踢成员。这是代码

const Discord = require("discord.js");
const { prefix, token } = require("./config.json");
const client = new Discord.Client();

client.once("ready", () => {
  console.log("Ready!");
});

client.on("message", (message) => {
  if (message.member.hasPermission(["KICK_MEMBERS", "BAN_MEMBERS"])) {
    if (message.content.startsWith(`${prefix}kick`)) {
      let member = message.mentions.members.first();
      member.kick().then((member) => {
        message.channel.send("```" + member.displayName + " has been kicked ```");
      });
    }
  }
});

client.login(token);

如果有人未经踢球和禁令许可而尝试，则不会发生任何事情，因此此部分正在运行。如果管理员输入例如：kick @someone然后有人会被踢。但是，如果管理员输入：kick（没有用户名），则会收到错误消息，并且该漫游器会停止工作，直到我手动将其重新启动为止。这是错误：TypeError：无法读取未定义的属性“踢”。我该怎么做才能使其完全正常工作？

您需要检查该用户是否存在。试试是这样的：

if (message.member.hasPermission(["KICK_MEMBERS", "BAN_MEMBERS"])) {
    if (message.content.startsWith(`${prefix}kick`)) {
      let member = message.mentions.members.first();
      if(!member) return message.channel.send('Cannot find this member');
      member.kick().then((member) => {
        message.channel.send("```" + member.displayName + " has been kicked ```");
      });
    }
  }

如果您想处理更多可能的错误，则需要使用try-catch块：

if (message.member.hasPermission(["KICK_MEMBERS", "BAN_MEMBERS"])) {
    if (message.content.startsWith(`${prefix}kick`)) {
      let member = message.mentions.members.first();
      if(!member) return message.channel.send('Cannot find this member');
      try {
        member.kick().then((member) => {
          message.channel.send("```" + member.displayName + " has been kicked ```");
        });
      } catch (error) {
        console.log(error);
        message.channel.send('An error has occured');
      }
    }
  }

在踢出该成员之前，检查用户是否提到了另一个用户：

const Discord = require("discord.js");
const { prefix, token } = require("./config.json");
const client = new Discord.Client();

client.once("ready", () => {
  console.log("Ready!");
});

client.on("message", (message) => {
  if (message.member.hasPermission(["KICK_MEMBERS", "BAN_MEMBERS"])) {
    if (message.content.startsWith(`${prefix}kick`)) {
      let member = message.mentions.members.first();
      if (!member)
        return;
      member.kick().then((member) => {
        message.channel.send("```" + member.displayName + " has been kicked ```");
      });
    }
  }
});

client.login(token);

你不能踢undefined。
