Jekyll doesn't recognize my custom plugin

Trying to learn how to write plugins in Jekyll. I created a simple gem after import i got this message

puts from custom plugin
Configuration file: /mnt/c/Users/_sectasy/Desktop/landing/_config.yml
  Dependency Error: Yikes! It looks like you don't have jekyll-test or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. If you've run Jekyll with `bundle exec`, ensure that you have included the jekyll-test gem in your Gemfile as well. The full error message from Ruby is: 'cannot load such file -- jekyll-test' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!
