Python 3.7

[pdr]

I've run into this before but I think you used eselect to fix it back then...

Latest "emerge -uavDN world" has an existing preserved lib: dev-libs/libffi -3.4.2-r1. Wants me to run "emerge @preserved-rebuild" to fix it. So I run:

Code: Select all

emerge -av @preserved-rebuild

and get back:

Code: Select all

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds to satisfy "dev-lang/python:3.7".
(dependency required by "@preserved-rebuild" [argument])

For (I assume) upcoming purposes, /etc/python-exec/python-exec.conf has "python3.9" in it. There is nothing in /etc/portage/package.use/ for python, nor in /etc/portage/make.conf (no PYTHON_TARGETS, etc). If I DO run "eselect python list", I get 3.9, 3.10 (fallback), and 3.8 (fallback). If I run "emerge -s dev-lang/python" the only installed are dev-lang/python (3.10.4), dev-lang/python-exec (2.4.9), and dev-lang/python-exec-conf (2.4.6).

Any help appreciated. I thought the other day when I first looked into this I found a python3.7 listed somewhere, but the output from "eselect python list" is a little concerning..

Plz run

Code: Select all

emerge -cav python:3.7

to find which package needs python37 and then unmerge them all.
Also you can run

Code: Select all

grep -ir python_*3_7 /etc/portage/package.use

to double check.
But it may not be a use flag but a hard dependency.
So the first command is better.

You should do world, depclean, then preserved-rebuild, as otherwise preserved will try to rebuild stuff which would otherwise get removed.
