Sass::SyntaxError: File to import not found or unreadable: bootstrap-sprockets

I am suddenly getting this error in development and in production on deployment.

custom.css.scss

@import \"bootstrap-sprockets\";
@import \"bootstrap         


        

Answer 1

This is how I solved the issue.

Go to Bootstrap for Sass Github page and follow the instructions:

1. Add the following to the Gemfile

   gem 'bootstrap-sass', '~> 3.3.6' gem 'sass-rails', '>= 3.2'

2. Run the command bundle install

3. Start/restart the server

   rails s

Also, make sure the file has .scss extension (or .sass for Sass syntax). If you have just generated a new Rails app, it may come with a .css file instead. If this file exists, it will be served instead of Sass, so rename it. Then, remove all the *= require_self and *= require_tree . statements from the sass file. Instead, use @import to import Sass files.

Answer 2

After making changes to Gemfile, do not forget to restart the server with rails s

Restarting the rails server worked like a charm! :D

Answer 3

I solved this issue by upgrading bootstrap-sass

gem 'bootstrap-sass', '3.2.0.2'

Answer 4

put this in gem file

gem 'bootstrap-sass', '~> 3.3.5'
gem 'sass-rails', '>= 3.2'

then run $ bundle install

Restart the server.

Answer 5

I have observed the same behaviour. In my case i have removed the version of the gem 'bootstap-sass' and it worked. There might be compatibility issue with the gem version which was causing the problem.

Gem file

gem 'bootstrap-sass'

After making changes in the gem file perform following commands:

bundle install

If the server is already running then stop it by "CTRL+C" and start the server again

rails s

Answer 6

This error mostly comes in rails 3.2.x versions. If you are using rails version 3.2 you have to specify a special version in your gem file like below:

gem 'rails', '3.2.0'
gem 'bootstrap-sass', '3.2.0.2'

It will resolve the problem for rails -v '3.2.0'
