oracle - 如何在 macOS Catalina 上使用 Oracle Instant Client 安装 Perl DBD::Oracle

Question

我正在运行 macOS Catalina 10.15.7，我需要安装 Oracle Instant Client 来运行连接到数据库的 Perl 脚本。

1。安装 Oracle Instant Client

我下载了我需要的包:

• 基本灯包 (DMG)
• SDK 包(DMG)
• ODBC 包 (DMG)

从 Instant Client 19.8 开始并遵循 installation instructions没有任何问题(只是复制和粘贴)

The files are extracted in /Users/username/Downloads/instantclient_19_8

2。设置 ORACLE_HOME

接下来，我将 ORACLE_HOME 设置为 /Users/username/Downloads/instantclient_19_8

export ORACLE_HOME=/Users/username/Downloads/instantclient_19_8

3。安装 DBD::Oracle

当我尝试安装 DBD::Oracle 时出现以下错误:

$ cpanm DBD::Oracle

live in their labelled sub-document (e.g., Win32
hints are gathered in 'lib/DBD/Oracle/Troubleshooting/Win32.pod').

Trying to find an ORACLE_HOME
Your DYLD_LIBRARY_PATH env var is set to ''

      The ORACLE_HOME environment variable is not set and I couldn't guess it.
      It must be set to hold the path to an Oracle installation directory
      on this machine (or a machine with a compatible architecture).
      See the appropriate troubleshooting guide for your OS for more information.
      ABORTED!

我读过 here ORACLE_HOME 应设置为包含 /bin 目录的目录的值，但我找不到任何 /bin。

macOS 一直在变化，但在 Mojave 上我从 DMG 安装了 Instant Client 然后做了:

brew install perl
ln -s $HOME/Downloads/instantclient_19_8 $HOME/instantclient
export DYLD_LIBRARY_PATH=$HOME/instantclient
cpan -i -T DBI
cpan -i -T DBD::Oracle

一般来说，永远不要为 Instant Client 设置 ORACLE_HOME。 (这可能导致读取错误的配置文件)。 ORACLE_HOME 用于“完整”数据库或完整客户端安装，而不用于即时客户端。然而，一些安装程序仍然引用该变量来查找构建文件，因此您将需要它 - 至少在构建时。 DBD::Oracle 将在内部搜索 Instant Client 并在未设置 $ORACLE_HOME 时使用 $HOME/instantclient。

macOS 逐渐删除了 DYLD_LIBRARY_PATH 的用处，因为它不会传播到子 shell。这意味着它不能可靠地使用。在 Mojave 上，我发现我可以选择将 Instant Client 库复制到 $HOME/lib/并且不需要设置 DYLD_LIBRARY_PATH。

旁注:如果您使用的是 DBD::Oracle，则不需要 Instant Client ODBC 包。
