我已经安装了 Spree gem 并按照入门中的说明运行它。一切正常，但如果我想进入管理面板的产品部分，我会遇到以下错误：

Mysql2::Error: Unknown column 'variants.position' in 'order clause': SELECT `variants`.* FROM `variants` WHERE (`variants`.product_id IN (706676762,569012001,723959550,1025786064,1060500592,248786582,187438981,1035865702,459084718) AND (variants.is_master = 0 AND variants.deleted_at IS NULL)) ORDER BY variants.position ASC

有人遇到过吗？

编辑：这是我的 Gemfile

source 'http://rubygems.org'

gem 'rails', '3.0.7'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'mysql2', '~> 0.2.11'
gem 'heroku'
gem 'thin'
gem 'spree', '~> 0.60.0'

# Use unicorn as the web server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

# To use debugger (ruby-debug for Ruby 1.8.7+, ruby-debug19 for Ruby 1.9.2+)
# gem 'ruby-debug'
# gem 'ruby-debug19', :require => 'ruby-debug'

# Bundle the extra gems:
# gem 'bj'
# gem 'nokogiri'
# gem 'sqlite3-ruby', :require => 'sqlite3'
# gem 'aws-s3', :require => 'aws/s3'

# Bundle gems for the local environment. Make sure to
# put test-only gems in this group so their generators
# and rake tasks are available in development mode:
# group :development, :test do
#   gem 'webrat'
# end
gem "test", :path => "test", :require => "test"

通常，当您按照以下步骤安装 spree 时，您应该在 db/migrate 中有一些迁移文件，其中一个包含您的应用程序缺少的列：

class AddPositionToVariants < ActiveRecord::Migration
  def self.up
    add_column :variants, :position, :integer
  end

  def self.down
    remove_column :variants, :position
  end
end
