OS X Lion with xampp + rails + mysql2 gem

Question

我一直在試圖弄清楚如何讓OS X Lion與XAMPP安裝的MySQL一起使用在rails2中的mysql2 gem。

這是我已經試過：

• 安裝了XAMPP開發套件
• 安裝MYSQL5服務器與兩個端口和啤酒。這兩個我現在卸載。因爲它沒有解決問題。從DMG文件
• 安裝MYSQL5社區版。現在卸載，因爲它沒有解決問題。
• 下載MYSQL5社區版的32位版本的焦油。提取的文件夾「在/ var/mysql的」

這裏是我正在試圖把它安裝了命令：

gem install mysql2 -- --with-mysql-dir=/var/mysql --with-mysql-include= 
/var/mysql/include --with-mysql-lib=/var/mysql/lib --with-mysql-config= 
/Applications/XAMPP/xamppfiles/bin/mysql_config 

我不知如何得到這個工作。我能想到的唯一的事情是我不知道如何正確指向目錄。我嘗試從with-mysql-include，with-mysql-dir和with-mysql-lib配置選項中刪除/ include /，/ mysql /和/ lib /。沒有那個運氣。我試過將它們指向XAMPP安裝。還沒有運氣。

返回的錯誤是：

Answer 1

這將會是最好不要用那東西XAMPP提供打擾，並只安裝MySQL的全新副本，並簡化您的寶石命令安裝mysql2：

brew install mysql 
gem install mysql2 

你通過，因爲這一切自制安裝MySQL安裝後的寶石均得到錯誤：

--with-mysql-dir=/var/mysql --with-mysql-include= \ 
/var/mysql/include --with-mysql-lib=/var/mysql/lib --with-mysql-config= \ 
/Applications/XAMPP/xamppfiles/bin/mysql_config 

因此，刪除它可以解決問題。
