安裝Spree ActiveRecord :: ConnectionNotEstablished錯誤

我想使用rails和spree gem（http://spreecommerce.com/）創建一個在線商店。安裝Spree ActiveRecord :: ConnectionNotEstablished錯誤

在我的Mac（os x lion）上留下了一段時間的rails開發，我使用本指南從零開始安裝了所有東西：http://tecparatodos.com/2011/07/24/installing-ruby-on-rails-on-mac-os-x-lion/和mysql與brew。

我也跟着狂歡的「入門文檔」 http://guides.spreecommerce.com/getting_started.html

所發生的問題是使用MySQL，配置數據庫和例如後做一個

rake db:create

我總是得到ActiveRecord :: ConnectionNotEstablished錯誤。首先，我認爲它與我的MySQL安裝有關，但經過幾個小時的檢查和重新安裝後，我發現它實際上是因爲狂熱的寶石。每當我將「gem'spree'」添加到我的Gemfile中時，就會發生此錯誤。當我刪除它並執行「捆綁安裝」時，一切正常。我有一些觀看項目的鐵軌體驗，但狂歡對我來說是新的。任何想法可能是什麼問題？

我的database.yml：

development: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: asiashop_development 
    pool: 5 
    username: root 
    password: 
    socket: /tmp/mysql.sock 

# Warning: The database defined as "test" will be erased and 
# re-generated from your development database when you run "rake". 
# Do not set this db to the same as development or production. 
test: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: asiashop_test 
    pool: 5 
    username: root 
    password: 
    socket: /tmp/mysql.sock 

production: 
    adapter: mysql2 
    encoding: utf8 
    reconnect: false 
    database: asiashop_production 
    pool: 5 
    username: root 
    password: 
    socket: /tmp/mysql.sock

當我做stracktrace 「導軌C」：

正如我寫的，它不能是一般的MySQL conenction問題，因爲一切正常罰款只要我不使用狂歡寶石。

您是否能夠爲此問題提供更大的堆棧跟蹤？你是如何配置你的'config/database.yml'的？你必須做了一些不同的事情，因爲Rails應用程序默認帶有sqlite3。 –

我使用的是沒有問題的mysql，只要我不使用狂熱寶石。我在上面添加了stracktrace和我的database.yml。謝謝！ –

您需要的寶石施普雷添加到您的Gemfile這樣：

gem 'spree', '0.70.3'

這將安裝最新的穩定版Spree。問題似乎是Bundler正在挑選Spree的一個非常舊的版本（0.40.0）來運行，這顯然是錯誤的。

默認不安裝最新版本的gem嗎？ – Lavixu

@Lavixu如果其他寶石的寶石依賴規格要求最新以外的其他寶貝，做'gem'spree''只是意味着「我想要任何版本的Spree」 –

真的不能查明問題的，但卸載所有寶石，然後從從頭開始重新安裝後，他們的來源，我得到它的工作..
