安装Mysql2 gem- 10.6服务器时出错
我正在尝试在10.6服务器上安装mysql2 gem，我收到一条错误消息，我没有看到：
EBuilding native extensions. This could take a while... ERROR: Error installing mysql2: ERROR: Failed to build gem native extension. /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb checking for rb_thread_blocking_region()... no checking for mysql.h... no checking for mysql/mysql.h... no ----- mysql.h is missing. please check your installation of mysql and try again. ----- *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

Results logged to /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6/ext/mysql2/gem_make.out 我已经尝试了几件事，指定内置MySQL的存储位置sudo gem install mysql2 -- --with-mysql-dir=/var/mysql ，并用预置的64-替换内置的mysql-来自mysql.com的位安装程序
有任何想法吗？
弄清楚了：
sudo env ARCHFLAGS="-arch x86_64" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
我发现你必须安装mysql-devel包…在Centos做yum -y install mysql-devel你很高兴。
我在使用RVM和“系统”Ruby解释器的OSX 10.5上遇到了同样的问题。 使用Ruby 1.8.7通过RVM修复了这种情况。
