Rails 4 + bootstrap set up assets

Question

I am trying to setup bootstrap on Rails4 using bootstrap-sass and I am getting this famous error:

Sprockets::FileNotFound - couldn         


        

Answer 1

The fix for me was two parts ... my correct list first ... but the list alone wasn't the fix!

gem 'sass-rails', '~> 5.0'
gem 'bootstrap-sass', '~> 3.3.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'

Then I had a gemfile.Lock issue ... if anyone else can't get the files to load & doesn't want to use the CDN...check your gemfile.Lock & see what versions are compiled off the gemfile (one is input for us as dev's & the other is what is actually ran by the framework - it will cause issues if you try to modify gemfile.lock).

To resolve the gemfile lock...close the gemfile & gemfile.Lock

1. I had to first delete the items in question from the "gemfile".
2. I did a "gem install " I wanted for each of them.

Then open the gemfile & gemfile.Lock to check results. Note, you still have to do all the configuration bootstrap etc requires for each of these. It doesn't hurt to run a rails assets:precompile either.

Note: The rails assets:precompile is a rails 5 command.
