ImageUploader:Class 的未定义方法“Include”（NoMethodError）

Question

我目前正在设置 Active_Admin 以便用户可以创建一篇文章并可以上传一张图片来说明它，使用载波（PaperClip 的问题太多了）。一切正常，直到我在 app/admin

中添加 'article.rb'

我现在无法在不收到以下错误的情况下启动服务器：undefined methodInclude' for ImageUploader:Class (NoMethodError)`，并且当我删除我的文件时错误没有出现.

这是我的上传者：

class ImageUploader < CarrierWave::Uploader::Base

  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  Include CarrierWave::MiniMagick

  # Choose what kind of storage to use for this uploader:
  storage :file
  # storage :fog

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end

  # Create different versions of your uploaded files:
  version :thumb do
    process resize_to_fit: [250, 0]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_whitelist
    %w(jpg jpeg gif png)
  end

end

这是我的管理文件夹中的 article.rb 文件

ActiveAdmin.register Article do
  form_for @article, :html => { :multipart => true } do |f|
    f.inputs "Article" do
      f.input :titre
      f.input :contenu
      f.input :image, :as => :file
    end
    f.buttons
  end
end

这是我的 Gemfile

source 'https://rubygems.org'

#base
gem 'rails', '4.2.5.1'
gem 'mysql2', '>= 0.3.13', '< 0.5'
gem 'sass-rails', '~> 5.0'

group :development, :test do
  gem 'byebug'
end

group :development do

  gem 'web-console', '~> 2.0'
end

gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw, :jruby]

#Gems installed after

#Contacts
gem 'simple_form'
gem 'mail'

#Admin
gem 'nokogiri', '1.6.8.rc3'
gem 'activeadmin', github: 'activeadmin'
gem 'formtastic', '~> 3.1', '>= 3.1.3'
gem 'devise'
gem 'carrierwave', '>= 1.0.0.beta', '< 2.0'
gem 'mini_magick'
gem 'friendly_id', '~> 5.1.0'

控制器没有任何用处，因为它只是用来显示文章。

我认为错误与 miniMagick 有关，因为这是我整个项目中唯一的 "include"，但是，我仍然需要调整一些图片的大小...

欢迎任何帮助

试试这个，

include CarrierWave::RMagick

或

include CarrierWave::MiniMagick

ImageUploader:Class 的未定义方法“Include”（NoMethodError）

undefined method `Include' for ImageUploader:Class (NoMethodError)
