NameError: uninitialized constant Carrierwave (Deploy to Heroku)

Question

我正在使用 Carrierwave 上传图片，但我遇到了一些问题：这是来自 heroku 的日志：

 Running `rake db:migrate` attached to terminal... up, run.2276

这是我的文件：

carrier_wave.rb:

    if Rails.env.production?
    Carrierwave.configure do |config|
        config.fog_credentials = {
            :provider => 'AWS',
            :aws_access_key_id => ENV['S3_ACCESS_KEY'],
            :aws_secrety_access_key => ENV['S3_SECRET_KEY']
        }
        config.fog_directory = ENV['S3_BUCKET']
    end 
end

Application.rb:

    require File.expand_path('../boot', __FILE__)

require 'rails/all'
require 'carrierwave'

Bundler.require(*Rails.groups)

module MagicRecipes
  class Application < Rails::Application

    config.autoload_paths += %W(#{config.root}/app/uploaders)

    config.serve_static_files = true

    config.active_record.raise_in_transactional_callbacks = true
    config.assets.initialize_on_precompile = false
  end
end

picture_uploader.rb

    class PictureUploader < CarrierWave::Uploader::Base


  include CarrierWave::MiniMagick
  process resize_to_limit: [600, 600]


  if Rails.env.production?
    storage :fog
  else
    storage :file

  end

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end


    def extension_white_list
      %w(jpg jpeg gif png)
    end



end

这是我的 Gemfile：

source 'https://rubygems.org'

gem 'rails', '4.2.0'
gem 'pg', '~> 0.18.1'

group :development, :test 做 gem 'byebug' gem 'web-console', '~> 2.0' gem 'spring' 结束

我的 gem 文件中安装了 gem 和版本。

我不知道问题出在哪里，我做了整个研究，但我可以解决问题。

谢谢

在您的 carrier_wave.rb 文件中，您的名称有错别字。将 Carrierwave 更改为 CarrierWave。如 documentation

NameError: uninitialized constant Carrierwave (Deploy to Heroku)

NameError: uninitialized constant Carrierwave (Deploy to Heroku)

linux

postgresql

ruby-on-rails
