Datamapper的dm_mysql_adapter gem是否支持Windows？

Question

我想用Ruby来玩更多，目前似乎掌握了sinatra，但现在也想从关系数据库中获取数据。我倾向于将Mysql用于测试应用程序，并尝试安装这些gem，但是当它试图编译它所依赖的原生do_mysql gem时，我一直收到异常。

我确实已经安装了本机扩展，并且它们对于JSON gem来说工作得很好，我记得之前在某个地方读到了do_mysql目前不支持Windows，所以只是想知道这是否仍然如此。

Mysql的5.5社区版安装并配置和MySQL的：

在Windows 7上使用Ruby 1.9.2

这里是例外柜面它有助于（通过安装红宝石+原生扩展安装）已被添加到系统PATH。

Answer 1

DataMapper和DataObjects（连接到数据库的较低层）做在Windows上工作。

然而，似乎do_mysql 0.10.7缺少预编译的二进制为x86-mingw32平台：

http://rubygems.org/gems/do_mysql/versions

可以do_mysql自己使用MySQL连接器/ C接口，它是独立的MySQL版本编译你已经安装在你的电脑中。

请看看这个博客帖子提供的安装说明：

http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/

的说明适用于mysql宝石，但将其更改为do_mysql应该工作（除示例代码是MySQL的具体。

希望帮助

到delinkify路易斯的回答，它看起来是这样的：

宝石安装do_mysql --platform =红宝石 - --with MySQL的-DIR = “C：/PROGRA~1/MySQL/MYSQLS~1.7/”

其中 “的MySQL-DIR” 路径是在x64系统的“C：\ Program Files”中的“MySQL Server 5.7”目录的简短版本。
