Errno :: <controllername>＃<actionname>中的ENOENT

Question

我尝试上传图片，但收到此错误：

所以这是我的控制器：

class RecipesController < ApplicationController
   def create
    @recipe = Recipe.new(recipe_params) 
    @recipe.chef = Chef.find(1) #temporal to use Gravatar

    if @recipe.save
        flash[:success] = "Your recipe was created successfully!"
        redirect_to recipes_path
    else
        render :new
    end
  end

  private

    def recipe_params
        params.require(:recipe).permit(:title, :summary, :description, :picture)
    end
end

我的模特

class Recipe < ActiveRecord::Base
  belongs_to :chef
  validates :title, presence: true
  validates :summary, presence: true
  validates :description, presence: true
  mount_uploader :picture, PictureUploader
  validate :picture_size

  private
    def picture_size
        if picture.size > 5.megabytes
            errors.add(:picture, "should be less than 5 MB")    
        end
    end
end

gem＆＃39; carrierwave＆＃39;，＆＃39; 0.10.0＆＃39; gem＆＃39; mini_magick＆＃39;，＆＃39; 3.8.0＆＃39;

两个Gems都在我的GemFile中，我在Windows上安装了ImageMagick。

ImageUploader.rb

class PictureUploader < CarrierWave::Uploader::Base

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

  storage :file

  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

希望你们能帮助我！
