I am relatively new to programming, therefore I hope that the question is not absolutely stupid.
I got a problem concerning my rails app.
I try to use bootstrap.
I got the same problem of "File to import not found or unreadable: bootstrap" in my scss file. I just solved by adding require statement of "bootstrap-sass" to config.ru file. My config.ru is like the following.
# This file is used by Rack-based servers to start the application.
require ::File.expand_path('../config/environment', __FILE__)
require 'bootstrap-sass' #require statement of bootstrap-sass
run Rails.application
