[SOLVED] no python-exec wrapped executable found ...

[charles17]

Playing around with python 3.6 => 3.7
Something went wrong and nothing works

Code: Select all

$ emerge --info
emerge: no python-exec wrapped executable found in /usr/lib/python-exec.

How could this be solved??

python-exec is just a wrapper, you can use emerge with absolute path

Code: Select all

$ /usr/lib/python-exec/python<version>/emerge --info

Works!
Thanks for the hint

If this is breaking a portage build, because it's being called by the build.
Emerging portage using the absolute path made it so I could run emerge -uavDN world again.

Hello.

I ran into the same problem when I tried to update @world and found a workaround that I would like to share.

The usual update command:

Code: Select all

emerge -DNuUva --with-bdeps-y @world

failed compiling `gobject-introspection` with the error message similar to this:

no python-exec wrapped executable found in /usr/lib/python-exec

I used to keep the python USE flags fixed as follows:

Code: Select all

*/* -python PYTHON_SINGLE_TARGET: -* PYTHON_TARGETS: -*

dev-python/* PYTHON_TARGETS: python3_7
app-portage/* PYTHON_TARGETS: python3_7
virtual/python-* PYTHON_TARGETS: python3_7
sys-apps/portage PYTHON_TARGETS: python3_7
...

So I guess when everything moved to python 3.9, the update process screwed things up because of the fixed python3_7 targets. Then I was unable to run `emerge` directly. Thanks to this forum thread I found that I still had an `emerge` executable at /usr/lib/python-exec/python3.7/emerge. But `/usr/lib/python-exec/python3.7/emerge portage` failed because of slot conflicts on dev-python/setuptools and dev-python/setuptools_scm.

After playing with the use flags and trying to reinstall different packages including python-exec and python-exec-config I got it. After unmerging dev-python/setuptools and dev-python/setuptools_scm and then re-emerging them I was able to emerge portage!

Code: Select all

USE='python_targets_python3_9 -python_targets_python3_6 -python_targets_python3_7 -python_targets_python2_7' sudo /usr/lib/python-exec/python3.7/emerge --unmerge -a dev-python/setuptools dev-python/setuptools_scm
USE='python_targets_python3_9 -python_targets_python3_6 -python_targets_python3_7 -python_targets_python2_7' sudo /usr/lib/python-exec/python3.7/emerge -a dev-python/setuptools dev-python/setuptools_scm
sudo /usr/lib/python-exec/python3.7/emerge -a portage

P.S.

Damn, I almost deleted Gentoo. A 10-year Gentoo user, I'm thinking of migrating to a binary distribution like Fedora
