为什么我的rails应用程序中默认的链接颜色发生了变化？

Question

我已经开始用rails编写一个应用程序，并注意到链接没有预期的颜色。链接的颜色是深灰色-蓝色，与标准的引导颜色不同，当我悬停在链接上时，它们的背景色是黑色的。为什么会发生这种情况？我猜这可能是我的宝石，下面是我添加的宝石：

gem 'devise'
gem 'devise-uncommon_password'
gem 'faker'
gem 'bootstrap-sass', '~> 3.3.6'
gem 'haikunator'
gem 'elasticsearch-model'
gem 'elasticsearch-rails'
gem 'kaminari'
gem 'bootstrap-kaminari-views'
gem 'acts-as-taggable-on'

无论何时运行rails scaffold命令，都会看到如下内容：

$ bin/rails generate scaffold HighScore game:string score:integer
    invoke  active_record
    create    db/migrate/20130717151933_create_high_scores.rb
    create    app/models/high_score.rb
    invoke    test_unit
    create      test/models/high_score_test.rb
    create      test/fixtures/high_scores.yml
    invoke  resource_route
     route    resources :high_scores
    invoke  scaffold_controller
    create    app/controllers/high_scores_controller.rb
    invoke    erb
    create      app/views/high_scores
    create      app/views/high_scores/index.html.erb
    create      app/views/high_scores/edit.html.erb
    create      app/views/high_scores/show.html.erb
    create      app/views/high_scores/new.html.erb
    create      app/views/high_scores/_form.html.erb
    invoke    test_unit
    create      test/controllers/high_scores_controller_test.rb
    invoke    helper
    create      app/helpers/high_scores_helper.rb
    invoke    jbuilder
    create      app/views/high_scores/index.json.jbuilder
    create      app/views/high_scores/show.json.jbuilder
    invoke  assets
    invoke    coffee
    create      app/assets/javascripts/high_scores.coffee
    invoke    scss
    create      app/assets/stylesheets/high_scores.scss
    invoke  scss
   identical    app/assets/stylesheets/scaffolds.scss

检查最后一部分，Rails创建一个scaffolds.scss文件，为您的模型创建另一个文件，默认情况下，模型的Rails文件不包含CSS规则，但是脚手架有，所以您可以尝试删除它。

您还可以尝试使用--no-stylesheets或--no-scaffold-stylesheet标志来不生成不必要的CSS文件。
