无法在Win 2008R2上安装Redmine .. gem install activerecord-mysql-adapter不起作用

Question

尝试在Windows Server 2008 R2上安装Redmine时，遇到了以下错误，我们没有找到解决方案...

它要求安装某些东西，并且在尝试安装时说找不到。 它建议使用activerecord-mysql2-adapter，但即使这样也不起作用...

我现在开始相信ROR很烂...

C:\Ruby\Apps\Redmine>rake db:migrate
rake aborted!
Please install the mysql adapter: `gem install activerecord-mysql-adapter` (193:
 %1 is not a valid Win32 application.   - C:/Ruby187/lib/ruby/gems/1.8/gems/mysq
l-2.8.1-x86-mingw32/lib/1.8/mysql_api.so)

Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)

Answer 1

根据您的database.yml adapter行，尝试使用gem install mysql或gem install mysql2 。

Answer 2

数据库连接中可能存在错误，请验证您的mysql是否正在运行，如果正在运行，请验证database.yml中的sql连接设置

我也遇到了这个问题，但是更改database.yml连接对我有用
