Ruby on rails 在ubuntu 14.04 x64上安装ruby-oci8时出错

我正在使用ubuntu 14.04 x64和以下环境变量：

export ORACLE_HOME=/usr/lib/oracle/12.1/client64
export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib
export PATH=$ORACLE_HOME/bin:$PATH

Sqlplus工作正常

但当我尝试安装ruby-oci8 gem时，系统返回以下错误：

bundle exec gem install ruby-oci8 --backtrace

有人知道会发生什么吗？

我记得大约两年前我在ruby-oci8上遇到过类似的问题，这是因为ruby-oci8不知何故不能与64位体系结构一起工作。我的解决方案是使用ruby 32位而不是64位

您是否遵循了以下步骤：

将Oracle与ruby结合使用是一件痛苦的事情，已经完成了：-）

更清楚地说，我所做的是：

下载oracle即时客户端32位

使用ruby 32位或x86_64安装ruby-oci8
