我想在Cygwin中安装DBD::Oracle模块。我已在C:Oracleinstantclient_12_1下载了Oracle Instant Client（12.1版）。我还下载了SDK和SQLPlus，并将它们提取到instantclient_12_1目录中。我将ORACLE_HOME路径设置为export ORACLE_HOME=/cygdrive/c/Oracle/instantclient_12_1，将LD_LIBRARY_path设置为export LD_LIBRARY_PATH=/cygdrive/c/Oracle/instantclient_12_1/lib。当我尝试安装软件包时，我会得到以下信息：
I'm having trouble finding your Oracle version number... trying harder
WARNING: I could not determine Oracle client version so I'll just
default to version 8.0.0.0. Some features of DBD::Oracle may not work.
Oracle version based logic in Makefile.PL may produce erroneous results.
You can use "perl Makefile.PL -V X.Y.Z" to specify a your client version.
Oracle version 8.0.0.0 (8.0)
DBD::Oracle no longer supports Oracle client versions before 9.2
Try a version before 1.25 for 9 and 1.18 for 8! at Makefile.PL line 271.

为什么安装程序无法检测到版本？我应该怎么做才能成功安装模块？
编辑：根据下面的建议，我尝试了perl Makefile.PL -V 12.1.0。我得到的输出是：

If sqlplus failed due to a linker/symbol/relocation/library error or similar problem
then it's likely that you've not configured your environment correctly.

但在make, make test and make install之后，模块仍然没有正确安装，我无法使用它运行任何脚本（make test返回37/38个失败案例）。我不知道该怎么办。
在以管理员身份运行CygWin终端后，我遵循了本指南，一切正常。
当然，你需要下载32位的win.zip版本，而不是.rpm文件：
- instantclient基本-*
- instantclient sqlplus*（有助于确定oracle版本）
- instantclient-sdk*
并将它们全部解压缩到例如c:\Oracle\
以管理员身份启动Cygwin终端并执行以下步骤：
export ORACLE_HOME=/cygdrive/c/Oracle/instantclient_12_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export ORACLE_DSN=DBI:Oracle:host=<oracle hostname>;sid=<oracle sid>
export ORACLE_USERID=user/password@<sid>
cpan get DBD::Oracle
cd到.cpan/build/DBD Oracle*文件夹中
perl Makefile.PL
make
make install
请与cpan DBD::Oracle核实安装情况。
你有没有试着按照说明说：
perl Makefile.PL -V 12.1.0
