Note: 目前仅支持linux和windows ；本项目使用了预构建，建议使用Node18，不需要编译而是从github下载编译好的文件，如果你电脑上的网络安装的时候无法访问github则会退化成编译。请安装项目中devDependencies依赖，在windows上编译可能遇到的问题可以参考这个链接https://blog.csdn.net/jjocwc/article/details/134152602

Note: windows requires wintun.dll If you do not trust this project Wintun.get_wintun_dll_path() provided dll can be downloaded to https://www.wintun.net/
