I have Mac OS X 10.5.7 with Python 2.5. I need to test a package I am working on with Python 2.3 for compatibility. I don’t want to downgrade my whole system so is there a way to do an install of Python 2.3 that does not change the system python?
You have two main options, install the python 2.3 from macports (easy) or install from source.
For macports, run
port install python23For the 2nd, you’ll have to go to http://www.python.org/download/releases/2.3.7/ to download the source tarball. Once you have that open a terminal and run
./configure --prefix /home/(your homedir)/software MACOSX_DEPLOYMENT_TARGET=10.5thenmakeandmake install. This should place a separate install in the software directory that you can access directly.
