Discord.js：未定义 MessageAttachment

Question

我无法让我的 bot 过滤消息并使用我计算机上的本地文件进行响应。代码如下：

      client.on("message", msg => {
      console.log(msg.content);
      let wordArray = msg.content.split(" ")
      console.log(wordArray)

      let filterWords = ['test']

      for(var i = 0; i < filterWords.length; i++) {
        if(wordArray.includes(filterWords[i])) {
          msg.delete()
          // Create the attachment using MessageAttachment
          const attachment = new MessageAttachment('cbcfilter.png');
          msg.channel.send(attachment)  
        }
      }
    });

它给了我这个错误信息：

    ReferenceError: MessageAttachment is not defined

        at Client.emit (events.js:323:22)

        at Receiver.receiverOnMessage (/Users/DShirriff/cbcbot/node_modules/ws/lib/websocket.js:801:20)

我是一个白痴并且缺少一个简单的括号，还是我应该寻找这行代码的不同形式？

您需要导入MessageAttachment。

如果您使用 require 导入 discord.js，那么您可以这样做：

const Discord = require('discord.js')
const attachment = new Discord.MessageAttachment('cbcfilter.png');

如果您使用的是import，那么您可以这样做：

import { MessageAttachment } from 'discord.js'
const attachment = new MessageAttachment('cbcfilter.png');

旁注：你不必构造MessageAttachment，你可以这样做

msg.channel.send({files: ['cbcfilter.png']})

或

msg.channel.send({
files: [{
    attachment: 'entire/path/to/cbcfilter.png',
    name: 'cbcfilter.png'
  }]
})
