安装Mysql2 gem- 10.6服务器时出错

Question

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.

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

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more

Provided configuration options:

    --ruby=/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
    --with-mysql-config
    --without-mysql-config


Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/mysql2-0.2.6 for inspection.

我已经尝试了一些东西,指定内置MySQL的存储位置sudo gem install mysql2 -- --with-mysql-dir=/var/mysql,并用mysql.com预构建的64位安装程序替换内置的mysql

有任何想法吗？

Answer 1

弄清楚了:

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

Answer 2

我发现你必须mysql-devel安装包装......在Centos 做yum -y install mysql-devel ,你很高兴去.
