What steps should I take to successfully load Bootstrap 4 on my web app?
Here is the contents of my Gemfile:
gem 'rails', '~> 5.1.5'
gem 'devise'
gem 'bootstrap-sass', '~> 3.3.7'
gem 'sass-rails', '>= 3.2'
gem 'coffee-script', '~> 2.4', '>= 2.4.1'
gem 'sqlite3'
gem 'puma', '~> 3.7'
gem 'autoprefixer-rails', '~> 8.1'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.2'
gem 'sprockets-rails', '~> 3.2', '>= 3.2.1'
gem 'turbolinks', '~> 5'
gem 'jbuilder', '~> 2.5'
This snippet is from Application.html.erb file:

I have previously faced issues related to coffee-script-source while trying to avoid the Exec.js error. To troubleshoot this, I installed Node.js on my computer, but unfortunately, Bootstrap didn't load as expected.
