mysql 似乎无法与我的新 Rails 应用程序配合使用
我似乎根本无法让 mysql 与我的新 Rails 应用程序一起使用...下面的终端副本：

What else should I try before reinstall Lion?

研究使用 Ruby Version Manager（称为 rvm），然后更新 Ruby。尝试使用 1.9 版本的 ruby 或更高版本。不要重新安装操作系统。如果有的话，移除导轨，移除红宝石。安装rvm，安装ruby 1.9，安装rails。如果你遵循这个食谱，一切都会好起来的。
将 Rails 配置为与 MySQL 一起使用将通过更改文件来实现：
这里有很好的信息：如何将 MySQL 设置为 Rails 3 中的默认数据库？
...此处：创建一个新的 Ruby使用 MySQL 而不是 SQLite 的 Rails 应用程序
习惯于查看 Rails 指南。像这样的例子： http://guides.rubyonrails.org/getting_started.html#配置数据库就是您开始所需的全部内容。
Look into using Ruby Version Manager (called rvm) and then update Ruby. Try using ver 1.9 of ruby or higher. Don't reinstall your OS. If anything, remove rails, remove ruby. Install rvm, install ruby 1.9, install rails. If you follow that recipe, all should be well.
Configuring Rails to work with MySQL will happen through changing the file:
Good information is here: How do I set MySQL as the default database in Rails 3?
... and here: Create a new Ruby on Rails application using MySQL instead of SQLite
Get used to looking at the Rails guides. Examples like this: http://guides.rubyonrails.org/getting_started.html#configuring-a-database are all you need to get going.
