Ruby on Railsレイクアセット：プリコンパイルエラー

Question

私はRails開発で新しく、これはHerokuへの私の最初の展開です。 私は（導入後）自分のアプリケーションを実行すると、エラーがあります：

2011-09-18T21:05:54+00:00 app[web.1]: Completed 500 Internal Server Error in 10ms 
2011-09-18T21:05:54+00:00 app[web.1]: 
2011-09-18T21:05:54+00:00 app[web.1]: ActionView::Template::Error (application.css isn't precompiled): 

私はこれをGoogleで検索し、私は自分の資産をプリコンパイルする必要があることがわかったが、これを実行しようとしたとき、私は他のエラーが見つかりました：

$ bundle exec rake assets:precompile RAILS_ENV=production 
rake aborted! 
No such process - /usr/lib/ruby/gems/1.8/gems/pg-0.11.0/lib/pg_ext.so 

(See full trace by running task with --trace) 

この問題の解決策はありませんでした。この問題に対処する方法を知っている人はいますか？

Answer 1

私も問題があります。しかし、あなたはローカルで、

rake assets:precompile RAILS_ENV=production 

を入力して、公開/資産でヒロクにプッシュすることができます。それは解決されました。

私もこの問題に走ったと私は次の操作を行って、それを解決し

Answer 2

：

はconfig/environments/production.rbを開き、以下のオプションがtrueに設定されていることを確認します

# Don't fallback to assets pipeline if a precompiled asset is missed 
config.assets.compile = true 

次に実行します。

を

rake assets:precompile --trace RAILS_ENV=production 

希望すると便利です。

Answer 3

私は新しいCedar stackを使用することをお勧めします。 Rails 3.1では、配備時の資産と全体のプレイをよりコンパクトにするために、アプリケーションを少しコンパイルする必要があります.Gemfileにいくつかの宝石を追加し、Procfileを作成する必要があります。しかし、それはまだ簡単な方法です。

Answer 4

ああ、これは簡単です。 PG宝石があなたのレーキ作業を壊しています。長い経路で修正しようとするか、プリコンパイルを実行するためにgemfileからコメントアウトしてみることができます。

Answer 5

PGの宝石の上に投稿されたSimpletonが問題を引き起こしているようです。もっと良い解決策は、あなたのgemfile内のPG gemをプロダクションの中に移動して実行することです。 バンドル生産 を--withoutインストールし、それがサービスに戻って、サーバーに指示しますので、その後、あなたは、config.assets.compile = true使用config.serve_static_assets = true

最初のオプションが間違っているの

Answer 6

代わりに問題なくrakeタスクを実行することができますapp/assetsフォルダー。

Answer 7

同じエラーメッセージがありました。私の問題は、間違って指定されたフォントのURLでした。

この回答の大部分は、私がそれをどのように理解したかを示しています。私が吐き出すために宝石を変更

** Invoke assets:precompile (first_time) 
** Invoke assets:environment (first_time) 
** Execute assets:environment 
** Invoke environment (first_time) 
** Execute environment 
** Execute assets:precompile

：私は

RAILS_ENV=production SECRET_KEY_BASE=xxx rake assets:precompile --trace 

を実行しているときに、それが失敗していた資産のパスを取得できませんでしたが

は、代わりに私は、このスタックトレースを持っていましたこの

のようなファイル名

subl /Users/smithd98/.rvm/gems/ruby-2.3.1/gems/sprockets-3.7.0/lib/sprockets/sass_processor.rb:124:in 

.btn-rect { 
    font-family: 'OpenSans-Light'; 
    src:font-url('fonts/OpenSans-Light.ttf') format('truetype'); 
} 

と持っている必要があります：私は

RAILS_ENV=production SECRET_KEY_BASE=xxx rake assets:precompile --trace 

を実行したときに

def asset_path(path, options = {}) 
    path = path.value 
    puts path 
    puts '123' 

    path, _, query, fragment = URI.split(path)[5..8] 
    puts '126' 
    path  = sprockets_context.asset_path(path, options) 
    puts '128' 
    query = "?#{query}" if query

    fragment = "##{fragment}" if fragment 
    puts '132' 
    Autoload::Sass::Script::String.new("#{path}#{query}#{fragment}", :string) 
    end 

は、その後、私はその後、私は、問題は、フォントは次のように指定されていただった

** Invoke assets:precompile (first_time) 
** Invoke assets:environment (first_time) 
** Execute assets:environment 
** Invoke environment (first_time)
