@yibie I'd suggest asking this on a ruby-language-specific forum. But also if you're having trouble installing psych, you may just need to install libyaml. Good luck!

Thank you, because I'm not familiar with Ruby, I don't know what happened. Thank you for your detailed and concise answer. I'll know where to post appropriate questions in the future.
