私は本番環境に配備しようとしているRailsアプリを持っています。私はnginxので旅客を設定している、とnginxのログを見て、乗客が開始されたが、私は私のアプリを閲覧しようとすると、エラーログには、次のようにいっぱいになった:RailsアプリがPassenger + Nginxで読み込まれない

私は/ tmpにチェックインした/しかし、 /tmp/passenger-error-okz7mL.html ファイルがありません。私のシステムRubyは2.4.2です。これは私のアプリケーションが使用しているのと同じで、RVMバージョンと同じものです。

問題がどこにあるのかわかりません。私の宝石は、アプリとシステムで最新の状態です。

私は乗客のエラーページを読み込むことができますが、それ以外のものは読み込めません。

私はriendlyエラーページを有効にして、以下の出力を持っている:

申し訳ありません。別の質問にコメントしていた。あなたはbundlerの宝石をインストールしましたか? –

はい、 'gem install bundler'を使ってください – Luke

さて、あなたは' bundle exec rails c production'を実行できますか?何かエラーがありますか? –

旅客は/usr/bin/rubyを使用している、あなたはそれがRVMのRubyを使用します。あなたのシステムには複数のRubyインタプリタがあるので、あなたのアプリを実行するためにRubyのどのコマンドを使うべきかをPassengerに伝える必要があります。どのRubyインタプリタを使用しているか調べるには、passenger-config about ruby-commandを実行してください。たとえば:

passenger-config about ruby-command 
passenger-config was invoked through the following Ruby interpreter: 
    Command: /usr/local/rvm/gems/ruby-2.3.3/wrappers/ruby 
    Version: ruby 2.3.3p85 (2015-02-26 revision 49769) [x86_64-linux] 
    ... 

(この例では、/usr/local/rvm/gems/ruby-2.3.3/wrappers/ruby)「コマンド」の後にパスをメモしてください。このパスにpassenger_ruby設定オプションを設定する必要があります。
