Rails 6 webpack how include vendors?

[galievruslan]

Hello
I want to connect the gentelella template to my rails 6 project.
The project is completely empty.
Installed via yarn add gentelella.
Further in the file app / javascript / packs / application.js added
require ("gentelella")
But when you open any page, it gives an error that Jquery is not connected. If I understand correctly all the dependencies should have been connected from the vendors folder but this did not happen, at least for rails 6 it works for a friend.
Tell me how to properly connect all the dependencies so as not to install them manually.

Can you verify that you're initializing jquery in your Rails 6 app per instructions in the gem's readme? https://github.com/rails/jquery-rails
