狂潮發電機不工作時，類型'rails g spree網站'

嗨，我是一個開發rails應用程序的新手，我有興趣使用'狂歡'爲我的電子商務網站。狂潮發電機不工作時，類型'rails g spree網站'

我下面這個教程大禮包從這個網站 http://guides.spreecommerce.com/getting_started.html

我做了一個新的安裝爲上面的教程指導我。我使用rails 1.9.3和mysql 數據庫將其作爲'5.1啓動Spree'的一部分。一切都很好，直到我注意到登錄欄不是像教程那樣出現。
我做了一些研究，害得我到這個解決方案中 https://github.com/railsdog/deface/issues/12 我從這篇文章中瞭解，似乎問題使用Ruby 1.9.3，當來自從污損寶石一個「錯誤」，但問題不會出現在1.9.2中，因此我將ruby 版本更改爲1.9.2以試用它。
在我安裝了ruby 1.9.2後，我安裝了'spree'gem，我重複了'入門教程'中的項目（使用mysql數據庫）來完成教程。
現在在部分4.4.2，其中i型 '耙分貝：創建' 端子輸出本

商店$耙分貝：創建

store_test已經存在
store_development已經存在
當我試着通過'rails g spree：site'生成狂歡網站，終端給我這個錯誤

我很迷惑，因爲我沒有之前創建一個數據庫（但它顯示出它的存在）。而現在我甚至不能生成狂歡網站。我研究了這個問題幾天，我還沒有找到一個匹配解決方案。這是我的Gemfile看起來像

源「http://rubygems.org」

gem 'rails', '3.1.2' 

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

gem 'mysql2' 


# Gems used only for assets and not required 
# in production environments by default. group :assets do gem 'sass-rails', '~> 3.1.5.rc.2'  gem 'coffee-rails', '~> 3.1.1' 
gem 'uglifier', '>= 1.0.3' end 

gem 'jquery-rails' 

# To use ActiveModel has_secure_password 
# gem 'bcrypt-ruby', '~> 3.0.0' 

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

# Deploy with Capistrano

# To use debugger

group :test do # Pretty printed test output gem 'turn', '0.8.2', 
:require => false 

gem 'spree' , '0.70.2'
