紅寶石LoadError mysql2/mysql2需要

Question

我試圖在OSX 10.8上設置我的Rails服務器，但我無法讓我的Rails服務器運行。
- 目前我在MySQL 5.1中使用Zend Server。
- 我也有istalled brew和brew mysql。
- 我用：
gem install mysql2 -- --srcdir=/usr/local/mysql/include --with-opt-include=/usr/local/mysql/include
服務器已經工作，但現在，我總是得到這個loadError下面。

這是我的Gemfile說什麼：

而且開始rails s

THX對於任何幫助後！

Answer 1

檢查該解決方案：

• http://railsforum.com/viewtopic.php?id=50501
• rake db:migrate giving error for mysql2

Answer 2

之後，我改變了我的database.yml如下：

development: 
    adapter: mysql2 
    socket: /usr/local/zend/mysql/tmp/mysql.sock 
    #host: 127.0.0.1 

讓我用我的地方zend MySQL套接字。 在我的情況下， 「」 無法連接到MySQL服務器上的 '127.0.0.1'（61）（Mysql2 ::錯誤）」就不見了。
