Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Disclaimer: I'm running Arch Linux, not ubuntu, but that should be irrelevant, or if it isn't I should be able to translate from apt to pacman.

Whenever I attempt to use an application relating to python2(gnome-tweak-tool, bzr, etc.) it fails to start and, when run from command-line, I get this error:

    [username@host ~]$ gnome-tweak-tool
Traceback (most recent call last):

    raise IOError(msg)
IOError: invalid Python installation: unable to open /usr/bin/lib/python2.7/config/Makefile (No such file or directory)

I checked /usr/bin/lib/python2.7/config/ and it is empty.

Its input/output error for system related issue such as file or directory not found/exist docs.python.org/library/exceptions.html#exceptions.IOError. Could you elaborate on what you are trying to achieve? –  sagarchalise Feb 18 '12 at 3:49

AFAIK /usr/bin should not have a lib folder as libraries are provided from /usr/lib folder. May be you should pass some argument for paths to look for during installation ? By the way gnome-tweak-tool is provided through arch official repositories so it should work unless you are trying a different tweak-tool ? –  sagarchalise Feb 18 '12 at 4:00
    
Yeah, there's definitely something we're missing here. It should be /usr/lib, not /usr/bin/lib. Something was definitely mistyped at some point. Can you just run the python command? –  Ken Feb 18 '12 at 17:13
    
This is offtopic here on Ask Ubuntu, I suggest you ask on Unix and Linux instead.. –  jrg Feb 19 '12 at 2:36
    
Moving to Unix and Linux. –  fwhiffahder Feb 23 '12 at 19:57
