RUBY：无法在Ruby 2.1.5p273（Windows 8.1）上安装0ci8库并连接到Oralce

我面临着严重的限制和问题（我猜是与操作系统有关），我也在Ruby的一个中查看了很多论坛，但并没有给他们带来太大的帮助;我真的认为社区没有真正的支持或API /库可用性 .

细节：

Ruby版本：2.1.5p273

Ruby路径：C：\ Ruby21 \ bin

宝石版：2.2.2

操作系统：Windows 8.1 64位

ORACLE版本：Oracle Database 12c企业版12.1.0.1.0版 - 64位 生产环境 版

Oracle：D：\ app \ username \ product \ 12.1.0 \ dbhome_1

在CMD

gem install ruby-oci8  --source http://rubygems.org

但很多错误：

为什么我需要这个？

我正在使用CSV文件，数组和 Map 进行一个小练习...但我的解决方案将完美地使用真正的数据库表和参考完整性......但我担心我将在红宝石中安装oci8：

我展示了一个失败的代码示例

require 'oci8'


#sqlplus fred/fred@localhost:1521/DB1


oci = OCI8.new('fred','fred','localhost:1521/DB1')
oci.exec('select sysdate from dual') do |record|
  puts record
end


ERROR in Eclipse Luna:
