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.

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

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？

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

我发现你必须安装mysql-devel包...在Centos做yum -y install mysql-devel你很高兴去。

Answer 3

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。
