我是 RoR 编程新手。我在尝试在简单的 RoR 项目上启动 webrick 网络服务器时遇到错误，同时在提示命令行中键入以下代码：

“轨道服务器”

我收到了这个错误：

我从这里（和许多其他人）尝试了解决方案： Ruby mysql2 Error http://railsforum.com/viewtopic.php?id=50501 他们没有用。

我的细节：

windows 7 64 bit
mysql  Ver 14.14 Distrib 5.5.28, for Win64 (x86)
ruby 1.9.3p327 (2012-11-10) [i386-mingw32]
Rails 3.2.9
gem 1.8.24

由于此链接，提示命令：“rails server”再次运行：

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

这对于在 Windows 7 X64 上正确安装 mysql 和 rails 非常有帮助。

您需要从 MySql 安装目录中复制libmysql.dll并将其粘贴到ruby​​193/bin ....
