Rails，MySQL和Snow Leopard

Question

我使用在WWDC上获得的光盘升级到了雪豹。

现在尝试运行我的一些Rails应用程序会抱怨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.

!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.
rake aborted!

(See full trace by running task with --trace)

我本可以发誓我曾经修复过这个问题。问题是

sudo gem install mysql

不起作用并给出错误：

ERROR:  Error installing mysql:

有没有人得到mysql在雪豹上使用Rails呢？如果是这样，您的设置是什么，更好的是，我该怎么做才能重现它？

Answer 1

我经历了同样的痛苦…这对我有用：

1. 从mysql.com下载/安装64位MySQL 5.1.37
2. 运行以下命令：

   sudo gem update --system
   
   sudo env ARCHFLAGS =“-arch x86_64” gem install mysql---with-mysql-config = / usr / local / mysql / bin / mysql_config
   

我还卸载了从10.5天开始浮动的所有mysql gem，如果上述方法对您不起作用，则可以这样做：)
