你需要的，如果你正在使用Rails 3.0.x的來鎖定您的mysql2版本在你的Gemfile：

gem "mysql2", "~> 0.2.11"

然後運行bundle install或bundle update mysql2。

編輯：

我注意到你是使用0.2.11版本的mysql2寶石。

仔細看，我注意到了這個錯誤：

Library not loaded: libmysqlclient.18.dylib (LoadError)

這可能表明，MySQL的開發頭文件/庫不可用。當您運行bundle install時，您的安裝mysql2 gem應該失敗。如果是這樣，你需要安裝這些開發庫，然後重新安裝gem。

Library not loaded: libmysqlclient.18.dylib (LoadError)

你需要在你的機器上安裝mysql。

如果你在終端輸入mysql會發生什麼？

也

如果鍵入 mysql --version到終端發生了什麼

是的，你需要gem的開發頭文件來編譯它看起來像，我不知道該怎麼做在mac上（你正在使用mac的權利？），但它不應該太難，去http://dev.mysql.com/downloads/mysql/，然後單擊開發版本選項卡，並下載適當的版本，作爲只要你安裝在系統默認位置，它應該工作 – loosecannon
