我按照 "http://blog.mmediasys.com/2011/07/07/installing-mysql-on-windows-7-x64-and-using-ruby-with-it/" 的方法，建立了 Ruby on rails 应用程序和 mysql server 5.1 之间的连接。

因此，我使用以下命令安装了 mysql gem：

gem install mysql --platform=ruby -- --with-mysql-dir=C:/mysql-connector-c-noinstall-6.0.2-win32

所以我得到了以下错误日志：

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

   C:/Ruby187/bin/ruby.exe extconf.rb --with-mysql-dir=C:/mysql-connector-c

-noinstall-6.0.2-win32 checking for main() in -llibmysql... no * 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.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=C:/Ruby187/bin/ruby
--with-mysql-dir
--with-mysql-include
--without-mysql-include=${mysql-dir}/include
--with-mysql-lib
--without-mysql-lib=${mysql-dir}/lib
--with-libmysqllib
--without-libmysqllib

Gem files will remain installed in C:/Ruby187/lib/ruby/gems/1.8/gems/mysql-2.9.1 for inspection. Results logged to C:/Ruby187/lib/ruby/gems/1.8/gems/mysql-2.9.1/ext/mysql_api/ge m_make.out

其他信息: Ruby版本1.8.7 Windows 7 64位操作系统 Mysql版本5.1

  1. 下载mysql/C连接器Zip文件。

  2. 将其解压到特定文件夹，如C: drive。

  3. 从mysql/C连接器Zip文件中复制libmySQL.dll。

  4. 尝试运行此命令：gem install mysql --platform=ruby -- --with-mysql-lib=C:\mysql-C-connector\lib --with-mysql-include=c:\mysql-C-connector\include
