And of course I can't delete Python 2.6.6 from the machine as a lot of system scripts depend on it. Any ideas what to do?


Solution

  • You will need to find a source for Python-3.4 packages, or build it yourself.

    A quick search finds http://wiki.guibin.info/?p=133 for building Python-3.4 yourself.

    With some more searching, you may be able to find a source for RPM packages, but of course it's up to you how much you trust those packages -- I wouldn't use a random RPM in production!
