Ruby on rails 无法通过rails连接到oracle

我在尝试通过RubyonRails连接到oracle时遇到了问题 ruby-r oci8-e oci8.new'hr'，password'.exec'SELECT*FROM jobs ORDER BY 1'{| r | put r.join}如下所示：

C:/RailsInstaller/Ruby1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/core_ext/kernel_re
quire.rb:46:in `require': incompatible library version - C:/RailsInstaller/Ruby1

        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/core_

        from C:/RailsInstaller/Ruby1.9.3/lib/ruby/site_ruby/1.9.1/rubygems/core_
ext/kernel_require.rb:46:in `require'

有人知道如何解决上述问题吗

提前感谢。

这将确保您安装的oracle客户端是32位的
