I try to run 'bundle install' and I get this error. I am trying to run specs for a school project testing me on Ruby on Rails associations among other things. The project uses pSQL, Ruby and RoR. I am able to run 'bundle install && ./setup_db.sh' in the active_record_queries folder but not in the associations folder for that is where I receive the above comment. When I run just 'bundle install' I receive: Your RubyGems version (2.7.6)) has a bug that prevents required_ruby_version from working for Bundler. Any scripts that use gem install bundler will break as soon as Bundler drops support for your Ruby version. Please upgrade RubyGems to avoid future breakage and silence this warning by running gem update --system 3.2.3

I also need to run ./setup_db.sh after as stated in the read me. Why am I getting this error message?
