upgradepkg uses wrong version of python for package installs

Question

I'm using slackware that has python 2.6 by default. I've installed python 2.7 and successfully insatlled numpy and scipy and matplotlib into python 2.7 using slackbuilds and pip.

However, when I try to install pygame using:

upgradepkg --install-new pygame-1.9.1-x86_64-1sl.txz

it installs to python 2.6 (the txz came from pkgs.org)

Is there a way to specify in upgradepkg which python version I want to us? I suppose the sure way is to unpack the pygame file, get into it and change some values, then repack it, then run the upgrade command again... but I don't really know what I'm doing so I wanted to see if there's a simpler way before I embark on that journey.

UPDATE: I'm having the same problem with PyGTK, so I'm starting to think it's something in the settings of upgradepkg... haven't been able to word the question right on Google to come up with a solution

Answer 1

That just means that the package was built for Python 2.6. Paths in packages are hardcoded, there is no way to change them. You have to rebuild the package from sources on your system, or find one that was made on a system with 2.7 installed.

Anyway, if all you need is Python stuff, have a look at pip: https://pip.pypa.io/en/latest/index.html
