问题描述：
因Flarum需要空白目录。而Let’s Encrypt添加ssl证书时会产生隐藏文件夹.well-known。
导致报错无法安装。
报错内容：
`[lighthouse@VM-8-10-centos 网站目录]$ composer create-project flarum/flarum .
Creating a “flarum/flarum” project at “./”
[InvalidArgumentException]
Project directory “/www/wwwroot/网站目录/.” is not empty.

试问有没有办法解决。
或只有更换ssl证书？
