discord.js MessageEmbedfields.flat不是函数 [英] discord.js MessageEmbed fields.flat is not a function

问题描述

我正在使用JavaScript和discord.js制作Discord机器人。在那里，我想向频道发送RichEmbed / MessageEmbed（我不知道如何称呼）。

I am making a Discord bot using JavaScript and discord.js. There, I want to send a RichEmbed/MessageEmbed (I don't know how it's called) to a channel. Instead of sending an Embed though, it threw an error inside discord.js.

TypeError: fields.flat is not a function
    at Function.normalizeFields (D:\discord-bot\node_modules\discord.js\src\structures\MessageEmbed.js:436:8)
    at MessageEmbed.addFields (D:\discord-bot\node_modules\discord.js\src\structures\MessageEmbed.js:252:42)

    at Object.module.exports [as MESSAGE_CREATE] (D:\discord-bot\node_modules\discord.js\src\client\websocket\handlers\MESSAGE_CREATE.js:4:32)

我已经在寻找答案，但似乎我是唯一遇到问题的人。

I searched already for an answer, but it seems like I'm the only person having trouble with it.

这是我使用的代码：

const embed = new MessageEmbed()
    .setTitle('Hello World')
    .setDescription('This is a test.')
    .setColor('#3498db')
quotes.forEach(quote => {
    embed.addField(quote.name, quote.description, true)
})
message.channel.send('Hello world.', embed)

推荐答案

如注释中所述，更新Node.js可解决此问题。 Discord.js v12需要12.0.0或更高版本，因为它用于提高效率的方法（例如错误中的 Array＃flat（））在旧版本中不存在

As discussed in comments, updating Node.js solves the issue. Discord.js v12 requires 12.0.0 or newer because of the methods (like Array#flat() in the error) it uses for efficiency which don't exist in older versions.
