.hasPermissions not working? Type Error: Cannot read property of undefined client?

Question

我和我的朋友们正在尝试制作一个 Discord 机器人。我们目前正在尝试发出踢球命令。但是，当我们尝试踢一个没有角色且只有基本权限的成员时，它不起作用并且此错误出现在 Repl.it 控制台上：

if(member.hasPermission("ADMINISTRATOR"))
                  ^

TypeError: Cannot read property 'hasPermission' of undefined
at Client.client.on.msg

然后是整个错误段落。

这是我们的代码：

我曾尝试寻找解决方案，但找不到任何解决方案。我发现的大多数网站都使用 has.Permission() 并且在 post 和 GitHub 上说使用 perm.has 但显然 "perm" 未定义。这是 Github post: https://github.com/AnIdiotsGuide/discordjs-bot-guide/blob/master/understanding/roles.md

const Discord = require('discord.js');
const client = new Discord.Client();
const token = process.env.DISCORD_BOT_SECRET;

client.on('ready', () => {
  console.log("I'm in.  My prefix is &.");
  console.log(client.user.username);
});

client.on('message', msg => {
    if (msg.author.id != client.user.id)
    {
      if(msg == "&help")
      {
        msg.channel.send("Here are some commands you can do! (prefix is &):");
      }    
      if (msg.content.startsWith("&kick")) 
      {
        if(member.hasPermission("ADMINISTRATOR"))
        {
          // Easy way to get member object though mentions.
          var member = msg.mentions.members.first();
          // Kick
          member.kick().then((member) => {
            // Successmessage
            message.channel.send(member.displayName + " has been successfully kicked!");
          }).catch(() => {
             // Failmessage
            msg.channel.send("Access Denied");
          });
        }
      }
    }
});


client.login(token);

您似乎没有设置 member 变量，或者您使用了不正确的变量来引用运行命令中的用户。

您可以将 member 变量设置为调用命令的成员，但由于您只使用它一次，所以最好直接使用它。

...
if (msg.content.startsWith("&kick")) 
      {
        // Get the member calling the command.
        if(msg.member.hasPermission("ADMINISTRATOR"))
...

请注意，如果此命令是运行在直接消息中，则给定的解决方案将导致问题。
