请到https://npm.taobao.org/mirrors/node/v16.2.0/ 下载Node.js运行环境。node-v16.2.0-darwin-arm64.tar.gz是M1 Mac的，node-v16.2.0-darwin-x64.tar.gz是Intel Mac的，win-x64/node.exe是Windows的。
去https://github.com/Sam0230/abook-downloader/releases/download/beta-05-23-2021/abook-downloader.bundle.min.js 下载bundle，Windows的使用方法不变，macOS是把abook-downloader.bundle.min.js移动到解压出的文件夹里的bin，右键bin，再选择 新建位于文件夹位置的终端标签页（接下来详见https://www.zhihu.com/question/267013491/answer/1902121086 ）
使用Node.js编写，依赖progress、request、string-width、performance-now模块。
abook-downloader.js是源代码，abook-downloader.bundle.min.js是打包好的bundle，可独立运行。packer.sh是打包器。
使用方法
sam0230@Sam0230-macOS:~/abook-downloader$ node-mac-arm64 abook-downloader.bundle.min.js (启动程序：前面的node-mac-arm64对不同的电脑来说不一样。node-mac-arm64是M1芯片上的macOS，node-mac-x64是Intel CPU上的macOS，对于大部分Windows用户，直接把下载下来的abook-downloader.bundle.min.js拖到node-windows-x64.exe上就行了，而M1 Mac上用虚拟机软件运行的Windows要用node-windows-arm64.exe。Linux用户用包管理器安装Node.js，然后node abook-downloader.bundle.min.js)
