我想我已尝试过每一个建议here。我也在运行Win7 x64。没有在MySQL服务器上进行任何开发，只需要远程连接到数据库
我正在运行Ruby 1.8.7
ruby --version
ruby 1.8.7 (2012-06-29 patchlevel 370) [i386-mingw32]
我尝试从“使用Ruby启动命令提示符”窗口运行安装（已经安装了几个宝石）：
gem list
*** LOCAL GEMS ***
addressable (2.2.8)
childprocess (0.3.3)
ffi (1.0.11)
libwebsocket (0.1.4)
multi_json (1.3.6)
net-sftp (2.0.5)
net-ssh (2.5.2)
net-ssh-gateway (1.1.0)
rdiscount (1.6.8)
rubyzip (0.9.9)
selenium-webdriver (2.24.0)
我没有运行Ruby on Rails，在我的环境中不需要（我不相信）。无论方法如何，结果仍然相同：
gem install mysql2 -- --with-mysql-include="C:\MySQL\include" --with-mysql
-lib="C:\MySQL\lib\"

我正在考虑在盒子上运行XP模式只是为了获得一个纯粹的32位环境，但这似乎是一个廉价的黑客。
困扰我的部分是“在-llibmysql中检查main（）...没有”这意味着（从我读到的）MySql应用程序和/或驱动程序不是安装正确。我尝试过不同的MySQL社区排列（是问题吗？）服务器32/64位或C连接器MSI / ZIP
有人能够在没有导轨的情况下运行吗？我本身并不进行Web开发，但希望使用Selenium来推动Web浏览会话。
