Question

ActionController :: RoutingError（没有路由与[GET]“ / system / images / avatars / 000/000/003 / small / rails.jpg％3F1416564723”匹配）

Answer 1

Just add it in Gemfile:

gem 'bootstrap-sass', '~> 3.2.0'
gem 'sass-rails', '4.0.3'

And execute:

bundle install

If you want use it - create custom file(.css.scss) in assets/stylesheets and write css using sass syntax.
