Issue with upgrade to bootstrap-sass 3.2.0

问题

Is there something else that needs to be referenced/configured when upgrading the bootstrap-sass gem to ~> 3.2.0?

Using RubyMine 6.3 as the editor and the following in the Gemfile:

ruby '2.1.2'  
gem 'rails', '4.1.1'  
gem 'sass-rails', '~> 4.0.3'  
gem 'bootstrap-sass', '3.1.1.1'  

app/assets/stylesheets/application.css.scss will be happy with

@import 'bootstrap';

However, once the bootstrap-sass gem is upgraded to its current version by changing the Gemfile reference to (and then running bundle update):

gem 'bootstrap-sass', '~> 3.2.0'  

RubyMine now has issues the @import 'bootstrap'; statement, saying "Cannot resolve import into sass/scss file".

The twbs/bootstrap-sass installation docs don't seem to infer that anything else is needed...

回答1:

Remove all the *= require_self and *= require_tree . statements from the sass file. Instead, use @import to import Sass files.

Do not use *= require in Sass or your other stylesheets will not be able to access the Bootstrap mixins or variables.
