我正在尝试在 10.6 服务器上安装 mysql2 gem，但收到一条我没有看到的错误消息：

EBuilding native extensions.  This could take a while...
ERROR:  Error installing mysql2:

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，并将内置 mysql 替换为来自 mysql.com 的预构建 64 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

我发现您必须安装该软件包mysql-devel...Centos 继续进行yum -y install mysql-devel ，一切顺利。

我在带有“系统”Ruby 解释器的 RVM 的 OSX 10.5 上遇到了同样的问题。通过 RVM 使用 Ruby 1.8.7 修复了这种情况。
