Question

我面临严重的限制和问题（我猜是与操作系统有关），我也在Ruby的一个中查看了许多论坛，但并没有真正的帮助来自他们;我真的认为社区没有真正的支持或API /库可用性。

详情：

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

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

CMD中的

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...但我恐怕我将在ruby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:

C:/Ruby21/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- oci8 (LoadError)
    from C:/Ruby21/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require'

Answer 1

Ruby-oci8为Windows提供二进制宝石。但是，--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gems（版本2.1.7）不包含ruby 2.2.1的扩展库。您应该使用ruby 2.1.5 (x64)。

辅助，如果您在运行SSL_connect returned=1 errno=0 state=SSLv3 ...（不 gem install ruby-oci8）时收到--source http://rubygems.org错误，请修正SSL错误（{{3} }）并再次运行gem install ruby-oci8。

Answer 2

异常消息：＆＃34;您必须先安装开发工具＆＃34;您需要安装devkit。

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