本文解释了出现constgzipHeader=Buffer.from([0x1f,0x8b])错误的原因，通常是因为使用了过旧的Node.js版本。解决方法是访问Node.js官方网站下载并安装最新版或推荐版本。

出现const gzipHeader = Buffer.from([0x1f, 0x8b])的错误是因为node的版本太低，可以到node官网（https://nodejs.org/en/）下载最新版或者官网推荐版本。

重新安装即可。

miniz：一个轻量级、高性能的开源压缩库
最新发布
红军不怕远征难，万水千山只等闲
07-25 834
miniz是一个轻量级开源压缩库，提供ZLIB/GZIP兼容的压缩/解压缩功能。其核心优势在于单文件实现（miniz.c+miniz.h）、跨平台支持和零依赖，编译后仅50-100KB。支持DEFLATE算法、9级压缩控制、CRC32校验及基础ZIP操作，适用于嵌入式系统、游戏开发等资源受限场景。与标准ZLIB相比，miniz体积更小但功能简化，性能良好但更适用于轻量级应用。使用简单，只需包含头文件并编译源文件即可，提供流式处理接口支持大文件操作。
