如何让jszip生成相同的缓冲区

Question

这是代码import JSZip = require('jszip');import crypto = require('crypto');let zip = new JSZip();zip.file("hello.txt", "Hello World\n");zip.folder("nested").file("hello.txt", "Hello World\n");zip.generateAsync({    type: 'nodebuffer',    mimeType: 'application/epub+zip',    compression: 'DEFLATE',    compressionOptions: {        level: 9    },})    .then(buf => {        const md5 = crypto.createHash('md5');        let result = md5.update(buf).digest('hex');        console.dir(result);    });如果运行此代码 2 次，将获得 diff md5当上下文相同时，如何使其成为相同的缓冲区
