在windows 7计算机上的ROR中安装Mysql Gem

我试图安装

mysql2

gem，但我看到了这个错误

我曾尝试将

llibmysql.dll

文件复制到

Ruby/bin

和

Ruby/lib

文件夹，但没有成功

请告诉我是否有人遇到过这个问题（我想这是针对Windows 7+ROR+Mysql的）

这对我来说很有效：

gem install mysql2 -- '--with-mysql-lib="c:\Program Files\MySQL\MySQL Server 5.5\lib" --with-mysql-include="c:\Program Files\MySQL\MySQL Server 5.5\include"'

我在windows上工作，很久以前我就放弃了在windows上使用rails（或django）。我使用带有Linux的虚拟机来运行我的开发环境。我强烈建议您也这样做，因为Windows上的许多外部库都会遇到很多错误。我认为Windows上的ROR应该是最糟糕的。我计划很快切换到Linux。。
