由于某种原因，我一直得到一个“TypeError：GridFsStorage不是构造函数”错误。我不知道为什么它给我这个错误，因为我只是按照官方文件。

存储上传

conn.once('open', ()=> {
    gfs = Grid(conn.db, mongoose.mongo)
    gfs.collection('uploads')
})

const storage = new GridFsStorage({
    url: DBURI,
    file: (req, file)=> {
        return new Promise((resolve,reject)=> {
            crypto.randomBytes(16, (err, buf)=> {
                if(err) {
                    return reject(err)
                }
                const filename = buf.toString('hex') + path.extname(file.originalname);
                const fileInfor = {
                    filename: filename,
                    bucketName: 'uploads'
                }
                resolve(fileInfo)
            })
        })
    }
})
const upload = multer({storage})

要求

const GridFsStorage = require('multer-gridfs-storage')
