Jekyll - Ruby 3.0 does not include webrick

bundle exec jekyll serve

When I tried to serve jekyll locally I get this.

cannot load such file -- webrick (LoadError)

 Incremental build: disabled. Enable with --incremental

..../.rvm/gems/ruby-3.0.0/gems/jekyll-3.9.0/lib/jekyll/commands/serve/servlet.rb:3
:in `require': cannot load such file -- webrick (LoadError)

Solution:

# This is because webrick is no longer a bundled gem in Ruby 3.0.
# let us add manually to our project

bundle add webrick
bundle exec jekyll serve

Hurray, It works !
