"bundler exec jekyll serve" creates error

[tasanyphy01773]

Hi. Thanks in advance for your help.
So I was trying to make my own portfolio with this repo. This is the error I get when commanding 'bundler exec jekyll serve'. System details are below. For more context, I get an error earlier that the system couldn't find mini racer, then I tried linking like this and it was solved, but now here I stuck.
