我与以下链接中讨论的问题几乎相同：

安装 Mysql2 gem-10.6 服务器时出错

我遵循了描述的解决方案，但我得到了这个：

sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
Building native extensions.  This could take a while...
ERROR:  Error installing mysql2:
    ERROR: Failed to build gem native extension.

mysql.h is missing.  please check your installation of mysql and try again.

    --with-mysql-config


Gem files will remain installed in /Users/angelos/.rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.3.7 for inspection.
Results logged to /Users/angelos/.rvm/gems/ruby-1.9.2-p290/gems/mysql2-0.3.7/ext/mysql2/gem_make.out

此外，我还尝试指定所有 mysql 路径：

sudo env ARCHFLAGS="-arch x86_64" gem install mysql --
--with-mysql-dir=/usr/local/mysql
--with-mysql-lib=/usr/local/mysql/lib
--with-mysql-include=/usr/local/mysql/include
--with-mysql-config=/usr/local/mysql/bin/mysql_config

仍然得到错误

$ sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-lib=/usr/local/mysql/lib --with-mysql-include=/usr/local/mysql/include --with-mysql-config=/usr/local/mysql/bin/mysql_config

Do you have the mysql header files actually installed in the paths you link to? Have you installed a package of mysql that includes the header file?

/usr/local/mysql

I have installed mysql with ports and I have it in /opt

$ find /opt -name mysql.h
/opt/local/include/mysql5/mysql/mysql.h

you could try

$ find /usr/local -name mysql.h

我回溯到 mysql 的 5.1.59 版本而不是 5.5，它运行良好。

看来 gem 仍然与 MySQL 5.5.xx 不兼容
