すべての道路はbootstrap-sassを指しています
紹介チェーン:
- railscast-328 (twitter ブートストラップの基本) は、
- http://www.sitepoint.com/twitter-bootstrap-less-and-sass-understanding-your-options-for-rails-3-1/を参照
- https://github.com/jlong/ sass-bootstrap は、sass するためのブートストラップの新しい公式ポートがあると主張しています。
- https://github.com/twbs/bootstrap-sassは、twitter-bootstrap 記事のオプションの 1 つです。
これは、bootstrap-rails gem の問題として報告されています: https://github.com/anjlab/bootstrap-rails/issues/91
正しくインストールしたと思います
宝石
gem 'sass-rails', '>= 3.2' # sass-rails needs to be higher than 3.2
gem 'bootstrap-sass', '~> 3.1.1'
インストールされている (アセット グループの外部と内部で試行)、application.css.scss には以下が含まれます
@import "bootstrap";
それだけ。
しかし、それは私にエラーを与えます
試行bundle exec rake assets:precompileすると、次のエラーが発生します。
rake aborted!
Undefined variable: "$alert-padding".

明らかな何かが欠けていると思います

- Rails の適切な SCSS アセット構造
- Railsアセットパイプライン以下でTwitterブートストラップを使用する
- https://github.com/twbs/bootstrap-sass/issues/79#issuecomment-4428595
- heroku で bootstrap-sass 経由でブートストラップをインポートしようとしましたが、エラーが発生しました

- railscast 328、329、268で手がかりを探す
- グーグルについて
- アンダースコアと .scss を使用するように gem の bootstrap/bootstrap.scss を変更する、 のアセットに関連する行をコメント アウトする
environments/production.rb、gem のページの 1 つだけにコメントするなどのさまざまな手直し (マニュアル)config.assets.initialize_on_precompile = true
問題が特定されました
gem の内容を assets ディレクトリにコピーしました。これは基本的に、jlong のブートストラップが行ったことです。
それは見ていませんapplication.css.scss...そこに入れたことを無視し、代わりにフォルダーを調べてそれらのファイルをロードすることを選択しました。これが、alerts.scss が最初に表示される理由です。_variables.scss の名前を _aavariables.scss に変更しようとしましたが、役に立ちませんでした
