[RUBY] What to do if you get angry if you don't have nokogiri while installing wp2txt

sudo gem install wp2txt

As a result of a lot of research and various trials, when I executed the following command posted on the official website, it was solved safely. It was a long battle ...

sudo apt-get install build-essential patch ruby-dev zlib1g-dev liblzma-dev
gem install nokogiri
