Blueprint CSS Rails 3.1ヘルプ

質問
私の青写真CSSは私のローカルマシンで動作しますが、ヘロクにプッシュするとエラーが発生します。
私には青写真が保存されています app/assets/stylesheets folder
そして、これが私が使用しているスタイルシートタグです:
<%= stylesheet_link_tag "application" %>
<%= stylesheet_link_tag 'blueprint/screen', :media => 'screen' %>
<%= stylesheet_link_tag 'blueprint/print', :media => 'print' %>
私のHerokuログでは、application.cssは事前縮小されていないと言っており、それがエラーかもしれませんが、それを修正する方法はわかりません。
これが私のHerokuログです:

解決
同じ問題がありました。設定して解決しました config.assets.compile = true
の config/environments/production.rb
編集:これは開発中に正常に機能しますが、実行時にコンピレーションが実行されるため、パフォーマンスペナルティがあります。より良い解決策については、以下の答えを参照してください
他のヒント
これを修正する1つの方法は、実行して資産を事前コンパイルすることです rake assets:precompile
. 。これには、JavaScriptランタイムを追加する必要があります
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'therubyracer'
gem 'sass-rails', " ~> 3.1.0"
gem 'coffee-rails', "~> 3.1.0"a
gem 'uglifier'
end
に Gemfile
そして実行します bundle install
.
あなたを設定してみてください:
config.assets.precompile += %w( blueprint/screen.css blueprint/print.css )
の config/environments/production.rb
私よりも経験がある人は、すべてのCSSファイルが標準として事前にコンパイルされていない理由を教えてくれると確信しています。私も始めたばかりです!
これが少なくとも1つの議論です:Rails 3.1アセットパイプライン - 公開/資産からファイルが欠落している - なぜこれがデフォルトではないのですか?
Rake Assets:Precompileを実行しようとしましたが、機能させることができませんでした。私はgemfileに資産グループを持っています。私はどこかで、生産を事前コンパイルすることを確認する必要があることを読みました:
RAILS_ENV=production bundle exec rake assets:precompile
それも助けにはなりませんでした。 config.assets.compile = trueを実行することになりましたが、これは正常に機能しましたが、実際のソリューションを機能させたいと思います。
