在做了下面的建议后,我仍然收到错误.

检查mysql_ssl_set()...是检查rb_str_set_len()...没有检查rb_thread_start_timer()...没有检查mysql.h ...是创建Makefile

您需要安装mysql dev库,因为mysql gem包含与它们链接的本机代码.在mac上最简单的方法是使用brew - 我已经使用过它并且它完美无缺,但是任何好的mac包管理器都可以工作(或者你可以从源代码安装mysql).

Brew安装:http://mxcl.github.com/homebrew/安装 完成后输入:

brew install mysql

默认情况下,所有brew收件人都安装dev库.
