在執行下面的建議後，我仍然收到錯誤消息。

檢查mysql_ssl_set（）...是 檢查rb_str_set_len（）...沒有 檢查rb_thread_start_timer（）...沒有 檢查mysql.h中...是 創建的Makefile

Answer 1

這應該是

sudo gem install mysql —- –-with-mysql-config=/usr/local/mysql/bin/mysql_config 

不

sudo gem install mysql — –with-mysql-config=/usr/local/mysql/bin/mysql_config 

（寶石名稱之間有兩個連字符和編譯選項，和兩個連字符前綴生成選項）

您可能還需要設置ARCHFLAGS變量。見here。

Answer 2

您需要安裝mysql開發庫，因爲mysql gem包含與它們鏈接的本機代碼。在Mac上最簡單的方法是使用brew - 我已經使用它並且工作完美，但任何好的mac軟件包管理器都可以工作（或者您可以從源代碼安裝mysql）。

釀造安裝：安裝它http://mxcl.github.com/homebrew/ 後只需鍵入：

brew install mysql 

所有BREW recipies默認安裝開發庫。
