composerinit命令详解

前言

今天安装了node&＃xff0c;准备用npm 下载项目所需要的依赖包
由于本人英语不太好&＃xff0c;在执行 composer init 命令后&＃xff0c;凭借着经验知道需要输入什么信息&＃xff0c;但还是不太明白&＃xff0c;也了解软件人性化的地方&＃xff0c;不输入肯定有默认值&＃xff0c;果然一通回车后&＃xff0c;居然 OK了&＃xff0c;当时感觉真的应了网上说的那句话 “一通操作猛如虎&＃xff0c;一看结果250”。
为了搞明白composer init命令后需要输入那些信息&＃xff0c;以及输入信息的规范&＃xff0c;我在下午详细介绍一下&＃xff1a;
