David Kimura PRO said 7 months ago on Failover Requests :
In the README.md of the template, I also share my railsrc dot file which includes

--css tailwind

as one of the flags. I believe this makes the difference between what you're experiencing and what I am doing.

If you were to run

rails new example --css tailwind -m path_to_template/tailwind.rb

then you should get the same results as I do.
