安装MySql2的问题gem

Question

我已经检查了这个网站上关于这个错误的许多主题，但是没有找到任何有用的东西。我对此很陌生。我正在使用Windows Server 2003 R2。

当我调用：

gem install mysql2 

我得到这个错误：

Temporarily enhancing PATH to include DevKit... 
Building native extensions. This could take a while... 
ERROR: Error installing mysql2: 
     ERROR: Failed to build gem native extension. 

     C:/Ruby192/bin/ruby.exe extconf.rb

*** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers. Check the mkmf.log file for more 
details. You may need configuration options.

     --with-mysql-lib 
     --without-mysql-lib=${mysql-dir}/lib 
     --with-libmysqllib

我有同样的问题。

在此之后link

我用命令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"'

，并为我工作。
