尝试过

gem install pkg-config
apt-get install libxml2-dev libxslt-dev zlib1g-dev -y
gem install nokogiri -- --use-system-libraries

但也没用，只能先卸载，再以gem方式来重装wpscan

pcat尝试过以apt方式来安装wpscan，但总会出现public_suffix的依赖冲突。

apt remove wpscan -y
apt-get autoremove -y
apt-get autoclean
hash -r
apt install ruby-dev -y
gem install wpscan

最后复制跑完发现，居然还要api，还是收费的，哎，不知道一下午干了什么。。。。。
