需要 mysql2 gem 时出现分段错误

Question

我一直在使用 1.8.7 开发一个 Rails 应用程序，现在正在尝试切换到 1.9.2（使用 RVM）。

但是，在切换 rubies、安装 Rails 并捆绑我的应用程序后，运行“rails s”会出现此错误（在 irb 中需要“mysql2”会出现相同的错误）：

/Users/kmurph79/.rvm/gems/ruby-1.9.2-p180/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle： [BUG] ruby​​ 分段错误 1.9.2p180（2011-02-18修订版30909）[x86_64-darwin10.6.0]

完整输出：

Abort trap

Mysql是通过自制软件安装的，并且在1.8.7下工作正常，但也许我需要安装新的mysql版本？我不知道。

非常感谢您的帮助。

我通过下载最新版本的MySQL解决了这个问题。
