puma無法在生產中啟動，引發無法加載應用程序：NoMethodError：＃的“ process” <Class:0x000000065f8ee8>

Question

我有一個Ruby on Rails應用程序，可以在開發中完美運行，但是一旦部署到生產環境，puma便無法啟動。 我整天都在調試和搜索此事，但無濟於事。

我嘗試從生產服務器上徹底清除該應用程序，然后從頭開始。 結果相同。

我嘗試過不同版本的彪馬-沒什么不同。

我嘗試以不同的方式訂購Gemfile-祝您好運。

我查找了ckeditor，mini_magick和carrierwave的已知問題，到目前為止，沒有發現任何有用的信息。

mekilacms寶石是我為該項目修改的Wellspring版本。 我還沒有發現與Wellspring相關的任何信息。

老實說，我的想法已經用完了。 非常感謝您對此提供的幫助。

這是puma.error.log，其中顯示了我遇到的問題：

=== puma startup: 2017-05-08 17:35:06 -0400 ===
! Unable to load application: NoMethodError: undefined method `process' for #<Class:0x000000065f8ee8>
Did you mean?  proc
bundler: failed to load command: puma (/home/www-data/apps/TrueSelfAcademy/shared/bundle/ruby/2.3.0/bin/puma)

無論是從Capistrano還是從作為部署用戶的命令行運行，都會發生這種情況。

這是在命令行上滾動的內容：

環境：Rails 5.0.1，Ruby 2.4.0rc1（2016-12-12 trunk 57064）[x86_64-linux]，Ubuntu Server 16.04（prod和dev-均已完全更新）rvm 1.28.0，bundler 1.14.6。

Capistrano版本：3.8.1（Rake版本：12.0.0）用於執行生產部署，該部署完成沒有錯誤。

這是Gemfile：

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")

為了便於閱讀，這里是資產模型。 我把它放在評論中，看起來很難看...

class Ckeditor::Asset < ActiveRecord::Base
  include ActiveRecord
  include Ckeditor::Orm::ActiveRecord::AssetBase
  include Ckeditor::Backend::CarrierWave
end

這是ckeditor_picture_uploader文件。 確實確實有puma抱怨的“過程”調用。 我目前正在查看資產路徑和資產預編譯...

class CkeditorPictureUploader < CarrierWave::Uploader::Base
  include Ckeditor::Backend::CarrierWave
  include CarrierWave::MiniMagick

  storage :file

  def store_dir
    "uploads/ckeditor/pictures/#{model.id}"
  end

  process :extract_dimensions

  version :thumb do
    process resize_to_fill: [118, 100]
  end

 version :content do
  process resize_to_limit: [800, 800]
 end

 def extension_white_list
  Ckeditor.image_file_types
 end

Answer 1

好吧，這很奇怪，但是已經解決了。

puma一直在抓緊的“處理”方法通常是在carrierwave gem中的uploader / processing.rb文件中定義的。

我之所以這樣說，是因為在我的不是。 我以某種方式結束了一個格式不正確的processing.rb文件，該文件不包含應有的“ process”（也不是邪惡的孿生“ process！”）。 我為這種情況的發生而費了腦筋，無法真正解釋它。

不過，獲取一份好的文件副本並用它替換格式錯誤的文件即可解決問題。

似乎幾乎是滑稽的，不是嗎？

無論如何，我要感謝@ Md.FarhanMemon和@SachinSingh抽出寶貴的時間回答並提出問題。
