我为Mac OS X Lion（来自.dmg）安装了MySQL 5.5.27。gem install mysql：无法构建gem原生扩展（Mac Lion）

现在，我尝试安装mysql的宝石：

$ gem install mysql

欧凯，这里是我的解决方案：

1) I installed homebrew. 
2) $ brew install mysql 
3) $ gem install mysql

这是所有。

在Linux上：'sudo apt-get install libmysql-ruby libmysqlclient-dev' – 2013-10-16 18:23:31

它看起来像宝石安装程序无法找到您的MySQL库/标题。

尝试指定MySQL目录，例如

gem install mysql -- --with-mysql-dir=/usr/local/mysql

（您可能需要搞清楚的是安装了MySQL的DMG分布在哪里，情况因人而异）

我试过你的解决方案，它不起作用。相同的输出。 – ExiRe 2012-08-09 11:01:17

你可以给创业板的安装路径mysql_config： '宝石安装mysql - --with-mysql的-配置=在/ usr /本地/ MySQL的/斌/ mysql_config' – jstr 2012-08-09 11:06:38

遗憾的是它并没有太多的工作：检查mysql_ssl_set（）...没有检查rb_str_set_len（）...没有检查rb_thread_start_timer（）...没有检查mysql.h ...没有检查mysql/mysql.h .. 。no *** extconf.rb失败***' – ExiRe 2012-08-09 11:08:12
