I recently cloned an existing repo I will be working on. The project uses Jekyll I installed ruby and followed each step from https://jekyllrb.com/docs/. When I go into the directory and type bundle exec jekyll serve, I get the error "Your Ruby version is 3.0.2, but your Gemfile specified 2.7.1". I use ohmyzsh and Zsh and I can't seem to figure out how to fix this issue. I don't want to mess with the gemfile. thank you.
The existing repository uses ruby version "2.7.1", but your installed and selected ruby version is "3.0.2". Please switch to ruby version "2.7.1" and then try again
