我一直在节点上制作一个服务器，它可以获取图像文件并在压缩后上传到磁盘上。但是，正在压缩较小尺寸的图像，而尺寸较大的图像（例如 10mb 左右）会出现以下错误。

 { Error: Error in file: ./uploads/ecqrwxgz6lw.jpg

我通过 multer 上传文件的代码是

    var multer = require('multer');

var storage = multer.diskStorage({
    destination: function (req, file, callback) {

        callback(null, './uploads');
    },
    filename: function (req, file, callback) {
        var  rand = Math.random().toString(36).substr(2, 12);
        req.rand =  rand;
        ext = file.originalname.substring(file.originalname.lastIndexOf('.'), file.originalname.length);
        callback(null, rand+ext);
    }
});

var upload = multer({
    storage: storage
}).single('userPhoto');

module.exports = {
    upload: upload,
};

这是我上传文件的路线

    app.post('/events/upload', upload, function (req, res) {

    var fb_id = req.user.id;
    var email = req.user._json.email;
    var random = req.rand;

    console.log(fb_id);

    var query = {
            'Fbid': fb_id
        },
        update = {
            $set: {
                email: email
            },
            $push: {
                events: {
                    event: place,
                    imageId: random
                }
            }
        },
        options = {
            upsert: true
        };

    usersuploadImformation.findOneAndUpdate(query, update, options, function (err, data) {
        if (err) {
            console.log("Not able to update");
        }
        else{
            console.log("Updated");
        }
    });


    imagemin(['./uploads/'+random+'.{JPG,jpg}'], './uploads', {
        plugins: [
            imageminMozjpeg({
                              quality: 60,
                              progressive: true

                             })
        ]
    }).then(files => {
        console.log(files);
        //=> [{data: <Buffer 89 50 4e …&gt;, path: 'build/images/foo.jpg'}, …] 
    }).catch((err)=>{
        console.log(err);
    });



});

刚刚使用了另一个压缩插件，这是 imageminmozjpeg 的错误。我使用了 imageminJpegRecompress
