铁路服务器错误？ （轨道3）在窗户
我使用命令创建了一个新项目：
rails new simple_cms -d mysql
但是当我尝试启动Web服务器时，会发生这种情况：
C:\Users\johnny\Sites\simple_cms>rails server C:/Ruby193/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/mysql2.rb:2:in `require': 193: %1 is not a valid Win32 application. - C:/Ruby193/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/1.9/mysql2.so (LoadError) from C:/Ruby193/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/mysql2.rb:2:in `' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2.rb:9:in `require' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2.rb:9:in `' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.1/lib/bundler/runtime.rb:68:in `require' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.1/lib/bundler/runtime.rb:68:in `block (2 levels) in require' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.1/lib/bundler/runtime.rb:66:in `each' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.1/lib/bundler/runtime.rb:66:in `block in require' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.1/lib/bundler/runtime.rb:55:in `each' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.1/lib/bundler/runtime.rb:55:in `require' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/bundler-1.1.1/lib/bundler.rb:119:in `require' from C:/Users/johnny/Sites/simple_cms/config/application.rb:7:in `' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.2/lib/rails/commands.rb:53:in `require' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.2/lib/rails/commands.rb:53:in `block in ' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.2/lib/rails/commands.rb:50:in `tap' from C:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.2.2/lib/rails/commands.rb:50:in `' from script/rails:6:in `require' from script/rails:6:in `' C:\Users\johnny\Sites\simple_cms> 一些版本信息以防万一：

我已经在网上搜索寻找解决方案，但它们似乎都不起作用。 非常感谢任何帮助，谢谢。
问题是运行mysql2所需的.dll文件不可用，因此，它不会将其识别为有效的Win32应用程序。
从官方存储库下载“mysql-connector-c-noinstall-6.0.2”。 您可能会被要求注册，但它是免费的。 转到下载，选择“MySQL Connectors => Connector / C（libmysql）”。
解压缩下载的文件，然后将位于lib文件夹中的“libmysql.dll”复制到Ruby / bin文件夹。
我在Mac上的服务器上遇到过类似的问题。 我更改了ruby的版本并且它有所帮助。 将ruby的版本更改为1.8.7并尝试它是否有效。
