Discord.js 无法读取属性 [英] Discord.js can't read properties

问题描述

我正在尝试使用 discord.js 发出禁令命令，但我无法使其工作.它总是回复无法读取未定义的属性(读取'有')"

I'm trying to make a ban command using discord.js, but I can't make it work. It always reply with "Cannot read properties of undefined (reading 'has')"

代码:

async run(message, args, client) {
    if (message.author.permissions.has(Permissions.FLAGS.BAN_MEMBERS)) {
        if (message.members.mentions.first()) {
            try {
                message.members.mentions.first().kick();
            } catch {
                message.reply("I don't have permission to ban" + message.members.mentions.first());
            }
        } else {
            message.reply("You cannot ban " + message.members.mentions.first());
        }
    }

}

我尝试查找一些示例代码，但它仍然不适合我

I tried looking up some sample codes but it still doesn't work for me

推荐答案

Message.author 是 User 实例，.permissions 没有不存在.使用 Message.member 来获取 GuildMember.

Message.author is a User instance, which .permissions doesn't exist on. Use Message.member instead to get the GuildMember.

另外，如 @user15517071 在 这条评论，你需要使用Message.mentions.members而不是Message.members.mentions

Also, as stated by @user15517071 in this comment, you need to use Message.mentions.members instead of Message.members.mentions

这是修改后的代码

async run(message, args, client) {
    if (message.member.permissions.has(Permissions.FLAGS.BAN_MEMBERS)) {
        if (message.mentions.members.first()) {
            try {
                message.mentions.members.first().kick();
            } catch {
                message.reply("I don't have permission to ban" + message.mentions.members.first());
            }
        } else {
            message.reply("You cannot ban " + message.members.mentions.first());
        }
    }

}
