I executed using Ruby 3.1:
gem install jekyll
Then I executed:
jekyll -v
And I got this error:
`require': cannot load such file -- sass-embedded (LoadError)
I tried to update ruby 3.1.2 to ruby-3.2.0-preview1, but I got more errors.
I installed sass-embedded:
gem install sass-embedded
It seems to be working fine now.
