错误信息：无法从 sqlplus 获取 Oracle 版本

Question

Ruby-oci8 gem 在 ubuntu linux 上构建时失败并显示以下错误消息，即使我将 LD_LIBRARY_PATH 和 ORACLE_HOME 设置为正确的路径。

*从 SQLPlus 获取 Oracle 版本... /ghostcache/nightly_build/components/ruby-oci8/akamai/ruby-oci8/ruby-oci8-2.2.1/ext/oci8/extconf.rb failed 由于某种原因无法创建 Makefile，可能缺少 必要的库和/或头文件。查看 mkmf.log 文件了解更多信息 细节。您可能需要配置选项。

知道这里缺少什么吗？

Answer 1

在我的例子中，我只需要在 ORACLE_HOME 下创建一个“bin”子目录，然后在那里创建一个指向 sqlplus 二进制文件的链接。
