Every time I run jekyll I get an error telling me to prepend it with bundle exec. Every time I run bundle exec jekyll (e.g. bundle exec jekyll build; bundle exec jekyll serve; etc.), I get a load error:
bundler: failed to load command: jekyll (/usr/local/lib/ruby/gems/3.0.0/bin/jekyll)
/usr/local/lib/ruby/gems/3.0.0/gems/kramdown-1.17.0/lib/kramdown/parser/html.rb:10:in `require': cannot load such file -- rexml/parsers/baseparser (LoadError)
