'twitter/bootstrap/responsive.less' wasn't found

Question

I am trying to move my application to another server, and I am currently getting the following error.

'twitter/bootstrap/responsive.less' wasn't found (in /home/rails/**/app/assets/stylesheets/bootstrap_and_overrides.css.less)

I don't have an :assets block in my gemfile -- so the previous solutions to this problem don't apply to my situation.

Here is my Gemfile

source 'https://rubygems.org'

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.1.1'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'
# Use SCSS for stylesheets
#gem 'sass-rails', '~> 4.0.3'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer',  platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'

gem 'twitter-bootstrap-rails'
gem 'bootstrap_form'

gem 'debugger'

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano-rails'

# Use debugger
#gem 'debugger'

Any help is appreciated! I'm more or less clueless regarding this error.

Additional Note: My application functions properly on my current server, but I cannot get it to run even once on my new server and I have tried to install it identically.

Answer 1

I inadvertently ended up updating twitter-bootstrap-rails to 3.2.0 when I didn't specify a specific version in my gemfile. The previous version was at 2.2.8, which I rolled back to and everything works just fine now. The new version is missing the responsive.less file.

Answer 2

The set up for version 3.2.0 of twitter-bootstrap-rails is different from version 2.2.8. If you want to use version 3.2.0 you must update the setup as well. To do so, run this command:

rails generate bootstrap:install less
