我正在尝试将 1 个图像覆盖在另一个图像的顶部，但似乎无法解决 - 我的代码没有引发错误，但没有输出请求的图像修改。有人可以指出我正确的方向吗？

这是我的代码

const user = message.mentions.users.first();

if (args[0] === undefined) {
    message.channel.send("You can't jail yourself, dummy!")
} else {
    var images = [user.avatarURL({ format: 'png', dynamic: true, size: 256 }), 'https://i.pinimg.com/originals/7b/51/9a/7b519a3422f940011d34d1f9aa75f683.png']
    var jimps = []
    //turns the images into readable variables for jimp, then pushes them into a new array
    for (var i = 0; i < images.length; i++){
        jimps.push(jimp.read(images[i]))
    }
    //creates a promise to handle the jimps
    await Promise.all(jimps).then(function(data) {
        return Promise.all(jimps)
    }).then(async function(data){
        // --- THIS IS WHERE YOU MODIFY THE IMAGES --- \\
        data[0].composite(data[1], 0, 0) //adds the second specified image (the jail bars) on top of the first specified image (the avatar). "0, 0" define where the second image is placed, originating from the top left corner
        //you CAN resize the second image to fit the first one like this, if necessary. The "100, 100" is the new size in pixels.
        data[1].resize(100,100)

        //this saves our modified image
        data[0].write(`\Users\jmoor\Pictures\JIMP Test\test.png`)
    })
    message.channel.send(`${user.username} has been jailed!`, {file: `\Users\jmoor\Pictures\JIMP Test\test.png`})
}

我已经在上面定义了 jimp，并且正在使用我制作的命令处理程序。

用这个：

    const user = message.mentions.users.first() //get The first user mentioned
    if (!user) return message.reply("Who do you wanna send to jail?")//return if no user was mentioned
    var bars = "https://i.pinimg.com/originals/7b/51/9a/7b519a3422f940011d34d1f9aa75f683.png"
    var pfp = user.avatarURL({ format: 'png', dynamic: true, size: 128 }) //get link of profile picture
    var image = await Jimp.read(pfp)//read the profile picture, returns a Jimp object
    //Composite resized bars on profile picture
    image.composite((await Jimp.read(bars)).resize(128, 128), 0, 0)
    //create and attachment using buffer from edited picture and sending it
    var image = new Discord.MessageAttachment(await image.getBufferAsync(Jimp.MIME_PNG))
    message.reply(image)
