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

Question

我面临严重的限制和问题（我猜是与操作系统有关），我已经在Ruby的一个中查看了很多论坛，但并没有真正给予他们很大的帮助; 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，数组和地图进行一个小练习......但我的解决方案将完美地使用真正的数据库表和参照完整性...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:

Answer 1

Ruby-oci8为Windows提供二进制gem。 但是当--source http://rubygems.org传递给gem install ruby-oci8时，它们不可用。

首先，您需要使用64位ruby才能使用64位Oracle。 请注意，最新的ruby-oci8二进制gem（版本2.1.7）不捆绑ruby 2.2.1的扩展库。 你应该使用ruby 2.1.5（x64） 。

辅助，如果你得到一个错误，如SSL_connect returned=1 errno=0 state=SSLv3 ...当你运行gem install ruby-oci8 （ 没有 --source http://rubygems.org ）时，修复SSL错误（ https ：//gist.github.com/luislavena/f064211759ee0f806c88 ）并再次运行gem install ruby-oci8 。

Answer 2

异常消息：“您必须先安装开发工具”您需要安装devkit 。
