[gentoo-user] python targets problem

[gentoo-user] python targets problem

[Philip Webb]

For a long time, several pkgs have been refusing to install,
apparently due to a conflict re python targets :

Can anyone else read this mess & advise what to do ?
Perhaps just leave well along ... (smile)

Why did you try these specifically? What does emerge -puDU world say?

What if you add dev-python/pygments to this list? This might be a stupid
guess, though... I'm too low on coffee to parse that emerge output.

(Also, do not forget --oneshot/-1, unless you really want to add those
to the world file.)

Here is some information that may help::

https://wiki.gentoo.org/wiki/Project:Python/Dependencies

It also often helps to just read the ebuilds relevant to the issues
you encounter. For example:

less /usr/portage/dev-python/setuptools/setuptools-36.7.2.ebuild

It's a pita, but as packages are listed in ebuild, check them out
(manually) on your system.


I had some issue with Python of late, and just settled  on the defaults
2.7 && 3.5 and they all cleaned up nicely.
