尝试在Windows Server 2008 R2上安装Redmine时，我发现以下错误，我们找不到解决方案......
要求安装一些东西，当试图安装它时说它找不到它。它建议使用activerecord-mysql2-adapter，但即使这样也行不通......
我现在开始相信ROR很糟糕......
C:\Ruby\Apps\Redmine>rake db:migrate
rake aborted!
Please install the mysql adapter: `gem install activerecord-mysql-adapter` (193:

取决于adapter尝试database.yml或gem install mysql的{{1}}行。

数据库连接可能出错，验证你的mysql是否正在运行，如果正在运行，请在database.yml中验证你的sql连接设置
我也遇到了这个问题，但更改database.yml连接对我有用
