Rails，MySQL和Snow Leopard
我使用我们在WWDC获得的光盘升级到Snow Leopard。
试图运行我的一些rails应用程序现在抱怨sql
(in /Users/coneybeare/Projects/Ambiance/ambiance-server)
!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.

我可以发誓我之前解决了这个问题。 问题在于
sudo gem install mysql
不起作用，并给出错误：

有没有人得到MySQL与雪豹铁轨工作呢？ 如果是这样，你的设置是什么，更好的是，我能做些什么来重现它？
我刚刚经历了同样的痛苦......这是对我有用的东西：
sudo gem update --system
sudo env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
我也卸载了所有从10.5天开始浮动的mysql gems，如果上述不适合你，那么可能会这样做:)
将64位重建为64位或安装64位版本非常重要，但您还需要确保将MySQL gem的本机部分构建为64位（如果您使用的是原始英特尔酷睿双核处理器之一，则这不适用） ）。
这是魔术命令：
env ARCHFLAGS="-arch x86_64" gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config
每当您在Snow Leopard上使用本地组件进行gem安装时，您应该如上所示设置ARCHFLAGS。
如果你使用的是Bundler，你可以使用“bundle config”为mysql设置正确的构建参数，如下所示：
bundle config build.mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config
