OS X Lion与xampp + rails + mysql2 gem

Question

我试图弄清楚如何使用XAMPP安装的MySQL获得OS X Lion以使用rails中的mysql2 gem.

这是我尝试过的:

• 安装了XAMPP Dev Kit
• 使用port和brew安装mysql5-server.我现在已经卸载了这两个.因为它没有解决问题.
• 从DMG文件安装mysql5社区版.现在已卸载,因为它没有解决问题.
• 下载32位版本的mysql5社区版作为tar.提取的文件夹为'/ var/mysql'

这是我正在运行以尝试安装它的命令:

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

我不知道如何让它发挥作用.我唯一能想到的是,我不知何故没有正确指向目录.我试过从with-mysql-include,with-mysql-dir和with-mysql-lib配置选项中删除/ include /,/ mysql /和/ lib /.没有运气.我已经尝试将它们指向XAMPP安装.还没有运气.

返回的错误是:

ERROR: Error installing mysql2:
ERROR: Failed to build gem native extension.

最好不要打扰XAMPP提供的东西,只需安装一个新的MySQL副本,并简化你的Gem命令来安装mysql2:

brew install mysql
gem install mysql2

通过Homebrew安装MySQL后,您在安装gem时出错,原因是:

--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

所以删除它解决了这个问题.
