美洲獅無法在生產中啓動，拋出無法加載應用程序：NoMethodError：`進程'爲＃<Class：0x000000065f8ee8>

我有一個Ruby on Rails應用程序，它在開發過程中運行完美，但一旦部署到生產，美洲獅失敗發射。我一直在調試和搜索這個問題整天，沒有用。美洲獅無法在生產中啓動，拋出無法加載應用程序：NoMethodError：`進程'爲＃<Class：0x000000065f8ee8>

我試過完全擦拭生產服務器的這個應用程序，並從頭開始。同樣的結果。

我試過不同版本的美洲獅 - 沒有區別。

我試着訂購不同的Gemfile - 沒有運氣。

我查了一下ckeditor，mini_magick和carrierwave的已知問題，到目前爲止還沒有找到有用的東西。

mekilacms寶石是我爲這個項目修改的一個版本。我還沒有發現任何有關Wellspring的事情。

老實說，我正在用盡想法。真的很感謝這一個幫助。

這裏是一個展示，我發現了問題puma.error.log：

=== 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)

發生這種情況無論是從Capistrano的，或者在命令行的部署用戶運行。

這是在命令行上滾動起來：

讓我知道是否有其他任何你需要看看......高興把它列入本帖子。

感謝您的幫助！ David

爲了便於閱讀，這裏是Asset模型。我把它寫在評論中，它看起來很難看...

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

這是ckeditor_picture_uploader文件。它確實有美洲獅所抱怨的「進程」呼叫。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

在整個應用程序中搜索'process'，你找到了多少？當然有一個流浪的人躺在.. –

添加'資產'模型的代碼。 –

@ Md.FarhanMemon正好有3個不在註釋中，所有3個都在一個名爲ckeditor_picture_uploader.rb的文件中。我在github的ckeditor gem頁面上查看了那裏記錄的問題。有趣的是，在生產中部署這個gem有很多問題，但到目前爲止他們所提供的修復都沒有解決我的問題。 –

嗯，這是不可思議的，但解決。

puma一直在持續的'process'方法通常在carrierwave gem的uploader/processing.rb文件中定義。

我說通常是因爲在我的，它不是。不知何故，我最終得到了一個格式不正確的processing.rb文件，它不包含'process'（也不是它的邪惡孿生過程！）。我對於這件事發生的事情感到緊張，並不能真正解釋它。

儘管如此，抓住文件的好副本，並用它取代我的畸形的文件解決了問題。

似乎幾乎是反胃，不是嗎？

無論如何，我還要感謝@ Md.FarhanMemon和@SachinSingh花時間回覆並提出問題。
