如何在Mac OSX上更改plpython使用的Python版本?

问题描述

我已经使用 EnterpriseDB 上的安装程序在Mac OSX 10.6上安装了PostgreSQL 9.0.4. a>，并注意到在plpython中实现的存储过程使用python 2.5.查看plpython库似乎可以证实这一点(在Mac上，otool类似于在Linux上ldd所做的事情):

I have installed PostgreSQL 9.0.4 on Mac OSX 10.6 using the installer from EnterpriseDB and noticed that stored procedures implemented in plpython use python 2.5. A look into the plpython library seems to confirm that (otool sort of does on the mac what ldd does on linux):

host:~ user$ otool -L /Library/PostgreSQL/9.0/lib/postgresql/plpython2.so
/Library/PostgreSQL/9.0/lib/postgresql/plpython2.so:
/System/Library/Frameworks/Python.framework/Versions/2.5/Python (compatibility version 2.5.0, current version 2.5.1)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.4)

host:~ user$ otool -L /Library/PostgreSQL/9.0/lib/postgresql/plpython2.so
/Library/PostgreSQL/9.0/lib/postgresql/plpython2.so:
/System/Library/Frameworks/Python.framework/Versions/2.5/Python (compatibility version 2.5.0, current version 2.5.1)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.4)

如何将其从Python 2.5更改为Python 2.6?

how can I change that from Python 2.5 to Python 2.6 ?

推荐答案

您需要从源代码进行重建.无法以二进制发行版对其进行更改.

You need to rebuild from source. There is no way to change it in a binary distribution.

运行configure时，将环境变量PYTHON设置为要使用的python二进制文件的完整路径，例如

When you run configure, set the environment variable PYTHON to the complete path of the python binary that you want to use, e.g.,

./configure --other-stuff ... PYTHON=/usr/bin/python2.6

我想，您可以尝试让EnterpriseDB人员来更新他们的构建例程.不知道他们选择什么标准来选择Python版本.或者，也许从MacPorts安装.

You could try to bug the EnterpriseDB people to update their build routines, I guess. Not sure by what criteria they choose the Python version. Alternatively, perhaps install from MacPorts.
