为什么？
另
rake db：create时，!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.

，怎么样才能把mysql给弄好？
[b]问题补充：[/b]
如果用
sudo apt-get install mysql
则会显示E: 无法找到软件包 mysql

那驱动呢，现在我只是想怎么解决我上面的问题啊，如果不行，怎么卸载我的mysql
sudo gem uninstall mysql 没有用

迁移数据库时，出现
rake aborted!
An error has occurred, all later migrations canceled:
Mysql::Error: Table 'activation_states' already exists: CREATE TABLE activation_states (id int(11) DEFAULT NULL auto_increment PRIMARY KEY, show_name varchar(10)) ENGINE=InnoDB
(See full trace by running task with --trace)
请问为什么，怎么解决？
Table 'activation_states' already exists
你在创建表的时候，这个表已经存在了啊，当然报错
先确保数据库中没有多余的表了哦
删除MySQL，试试下面的命令
[code="c"]sudo apt-get remove mysql
sudo apt-get autoremove[/code]
我在ubuntu安装的时候都是按以下方式来安装的哦
sudo apt-get install mysql
刚好下面这篇文章可以帮你啊
[url]http://letle.iteye.com/blog/258664[/url]
不会吧，我一直都是这么装的哦
要不你更新一下源吧
应该是
sudo apt-get install mysql-client
sudo apt-get install mysql-server
喜欢直观的话，可以使用新立得软件管理器来安装。
