Hello, my first time using Jekyll (for an online course) and also first time posting here. I’ve searched around for any solutions provided for the error I came across during my initial setup.
I wanted to preview the site after its first installation (I haven’t made any changes yet, I just wanted to preview it on my web browser), so I typed in the bundle exec jekyll serve on my Terminal. Unfortunately, this was what I got:

It’s supposed to give me an IP address that I can use to preview the newly-built Jekyll site on my browser, but I didn’t see it. I went ahead and entered bundle exec jekyll serve --trace and here are my results:

The ones that stood out for me from that error are bundler: failed to load command: jekyll (/Users/adriculous/.gem/ruby/2.6.0/bin/jekyll) and the last line: 1: from /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/socket.rb:201:in listen’

I don’t know how to fix these errors, so I decided to ask everyone here to guide me through these steps. Any suggestions on how I can fix this?
it looks like you have ruby installed in 2 places and it is confused. If you look at the output sometimes it is in /Library and other times it is in /System.
As I mentioned at the bottom of my original post, I’m using macOS (Big Sur). I read that it was already installed in my system, so I didn’t directly install ruby then. I also read that I shouldn’t use the ruby that’s already pre-installed in the system, so I installed ruby on another path.
I went ahead and installed ruby via Homebrew. I even changed the $PATH so that the system would read the ruby installed on that particular path. When I typed which -a ruby, it’s now installed in these two paths:
/usr/local/opt/ruby/bin/ruby
/usr/bin/ruby
When I entered which ruby in my Terminal, /usr/local/opt/ruby/bin/ruby came out as a result, so I thought that should fix it. I uninstalled and re-installed Jekyll and followed along the instructions and recreated a new project folder.
Once again, I want to view the newly-built site with bundle exec jekyll serve. It still didn’t work and gave me these errors:

I tried to add webrick gem install webrick. Then I attempted to run bundle exec jekyll serve again, then gave me the following result:
