Rails，MySQL和Snow Leopard?mysql

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. Importing all sounds in /Users/coneybeare/Projects/Ambiance/ambiance-sounds/Import 32/Compressed/

-- AdirondackPeepers.caf !!! 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! dlopen(/opt/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle, 9): Library not loaded: /usr/local/mysql/lib/libmysqlclient.16.dylib Referenced from: /opt/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle Reason: image not found - /opt/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle

(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：
