美洲狮无法在生产中启动，抛出无法加载应用程序：NoMethodError：`进程'为＃<Class：0x000000065f8ee8>

我有一个Ruby on Rails应用程序，它在开发过程中运行完美，但一旦部署到生产，美洲狮失败发射。我一直在调试和搜索这个问题整天，没有用。美洲狮无法在生产中启动，抛出无法加载应用程序：NoMethodError：`进程'为＃<Class：0x000000065f8ee8>

我试过完全擦拭生产服务器的这个应用程序，并从头开始。同样的结果。

我试过不同版本的美洲狮 - 没有区别。

我试着订购不同的Gemfile - 没有运气。

我查了一下ckeditor，mini_magick和carrierwave的已知问题，到目前为止还没有找到有用的东西。

mekilacms宝石是我为这个项目修改的一个版本。我还没有发现任何有关Wellspring的事情。

老实说，我正在用尽想法。真的很感谢这一个帮助。

这里是一个展示，我发现了问题puma.error.log：

=== puma startup: 2017-05-08 17:35:06 -0400 ===

发生这种情况无论是从Capistrano的，或者在命令行的部署用户运行。

为了便于阅读，这里是Asset模型。我把它写在评论中，它看起来很难看...

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

这是ckeditor_picture_uploader文件。它确实有美洲狮所抱怨的“进程”呼叫。我目前正在查看资产路径和资产预编译...

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

在整个应用程序中搜索'process'，你找到了多少？当然有一个流浪的人躺在.. –

添加'资产'模型的代码。 –

@ Md.FarhanMemon正好有3个不在注释中，所有3个都在一个名为ckeditor_picture_uploader.rb的文件中。我在github的ckeditor gem页面上查看了那里记录的问题。有趣的是，在生产中部署这个gem有很多问题，但到目前为止他们所提供的修复都没有解决我的问题。 –

嗯，这是不可思议的，但解决。

puma一直在持续的'process'方法通常在carrierwave gem的uploader/processing.rb文件中定义。

我说通常是因为在我的，它不是。不知何故，我最终得到了一个格式不正确的processing.rb文件，它不包含'process'（也不是它的邪恶孪生过程！）。我对于这件事发生的事情感到紧张，并不能真正解释它。

尽管如此，抓住文件的好副本，并用它取代我的畸形的文件解决了问题。

似乎几乎是反胃，不是吗？

无论如何，我还要感谢@ Md.FarhanMemon和@SachinSingh花时间回复并提出问题。
