【问题描述】：

我正在尝试在图片中做一些灰度效果，但是当我执行命令时，它会显示上面的错误...

有什么办法吗？

守则：

const jimp = require('jimp')
const {MessageAttachment} = require('discord.js')
module.exports = {
    name:'grey',
    run:async(client, message, args)=>{
        if (message.attachments.size > 0) {
            let image = message.attachments.first().url; 
            if(!image) return;
            let readedImage = await jimp.read(image);
            let sendedImage = await readedImage.greyscale()
            let attch = new MessageAttachment(sendedImage,'Skyy.png');
            message.channel.send(attch);
          }
        

    }
}

您必须在发送 jimp 图像之前将其转换为缓冲区：

const jimp = require('jimp')
const {MessageAttachment} = require('discord.js')
module.exports = {
    name:'grey',
    run:async(client, message, args)=>{
        if (message.attachments.size > 0) {
            let image = message.attachments.first().url; 
            if(!image) return;
            let readedImage = await jimp.read(image);
            // changed line below
            let sendedImage = await readedImage.greyscale().getBufferAsync();
            let attch = new MessageAttachment(sendedImage,'Skyy.png');
            message.channel.send(attch);
          }
        

    }
}
