I have been through the following links and have tried but didn't get any help:-
Cannot load Ruby EventMachine in Rails console - no such file to load
Using Live Reload with Jekyll
Unable to load the EventMachine C extension; To use the pure-ruby reactor
From the 2nd question mentioned above, I understand that --livereload comes with jekyll v3.7+.
My machine has the following:
Pkg / Cmd       Versions
---------       -------------------------------------------------------------
npm    -v       6.14.13
ruby   -v       ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x64-mingw32]
gem    -v       3.2.22
jekyll -v       jekyll 4.2.0
bundle -v       Bundler version 2.2.23
Now when I execute bundle exec jekyll serve or jekyll serve, I get the following output:-
PS C:\Users\Vedant\source\repos\Mine\phougatv.github.io> jekyll serve

    Server address: http://127.0.0.1:4000/

And when I execute bundle exec jekyll serve --livereload or jekyll serve --livereload, I get:
PS C:\Users\Vedant\source\repos\Mine\phougatv.github.io> jekyll serve --livereload

After getting the above-mentioned error I followed Answer-1 & Answer-2, and added gem "eventmachine" to the Gemfile but they didn't seems to solve my problem. One of these answers gave the error: 'require': cannot load such file -- sorted_set (LoadError), to resolve this I did gem install sorted_set(SortedSet has been removed), but then other error message was displayed. After trying all these answer, I think I am nowhere near to the correct approach.
Question: How do I execute: bundle exec jekyll serve --livereload or jekyll serve --livereload successfully?
