Hi all, I’m new to the command line and I am really struggling. My jekyll project was working until I did an update to rubygems with `gem update --system` and ever since I’ve had no luck executing any jekyll commands on previously built projects.

I receive `-bash: jekyll: command not found` when trying `jekyll serve` and when running `bundle exec jekyll serve` it returns `bundler: failed to load command: jekyll (/usr/local/lib/ruby/gems/2.7.0/bin/jekyll) Gem::Exception: can't find executable jekyll for gem jekyll. jekyll is not currently included in the bundle, perhaps you meant to add it to your Gemfile? /Users/will/.gem/ruby/2.7.0/gems/bundler-2.1.4/lib/bundler/rubygems_integration.rb:374:in `block in replace\_bin\_path’  
/Users/will/.gem/ruby/2.7.0/gems/bundler-2.1.4/lib/bundler/rubygems\_integration.rb:402:in `block in replace_bin_path' /usr/local/lib/ruby/gems/2.7.0/bin/jekyll:23:in `\<top (required)\>’

I get the feeling I’ve installed multiple version of Ruby improperly and messed up the path. I need some help to avoid a factory reset on my device ☹

I think so - it looks like you have ruby in both /usr and /users.

This seems to happen frequently, not sure why. Usually uninstalling and re-installing ruby seems to fix it.
