This is because you are overriding PYTHONPATH. If you run it as ...
LOG_LEVEL="DEBUG" PYTHONPATH="$(pwd)/my_project:$PYTHONPATH" python3 -m
pytest -m "my_test_marker" -s -vvv
... you might have better luck. Guix relies on PYTHONPATH to make
Python modules available because there is no single site-packages
directory like in some other distributions.
HTH!

Profiles for Python projects
Hi Guix Users!
Today I experimented a little with creating profiles from manifest.scm
file for Python projects. I have the following manifest.scm:
(specifications->manifest
'("python@3.8.2"
"python-falcon@2.0.0"
"python-levenshtein@0.12.0"
"python-jsonschema@3.2.0"
"python-pytest@5.3.5"))
I create a profile with that and it works fine:
guix package --manifest="manifest.scm"
--profile="${GUIX_EXTRA_PROFILES}"/my-env/my-env
Then I do the sourcing:
GUIX_PROFILE="${GUIX_EXTRA_PROFILES}/my-env/my-env"; source
"${GUIX_PROFILE}/etc/profile"
This also works fine and when I do:
which python3
#
which pytest
I also get a path in the profile I created. So far all seems to just
work. However, then I hit a snag when trying to run the tests of the
project:
LOG_LEVEL="DEBUG" PYTHONPATH="$(pwd)/my_project" python3 -m pytest -m
"my_test_marker" -s -vvv
I now get the error:
No module named pytest
So it seems, that somehow modules mentioned with
-m
Are not found. If I use PyTest without
python3 -m
in front, it also does not find libraries and I get errors for the
dependencies of the actual project.
Perhaps there is an easy fix for this. Has anyone used a Guix profile
like this before and knows how to make it work?
Regards,
Zelphir

Thanks for the heads up. I didn't get any errors or warnings that I see, so I guess everything is fine.

Well, it was even expecting that it works as '--with-source=https://example.org/foo.tgz'. All the best, simon

Actually all of 'frv' aren't needed but it's the combination of flags I use. It's remarkably common. ‘-r’ already implies ‘-f’ and stands for ‘really f[orce]’, which is my guess as to why so many brains remember ‘-rf’ instead.

Testing a new font
Hi, I'm new to Guix (still running in VM) trying to add a new font, but it doesn't show up in gnome-tweaks or other places. I added the font the font to fonts.scm, and ran $ ./pre-inst-env guix install font-iosevka-aile I can see the fonts in ~/.guix-profile/share/fonts/truetype, but it doesn't seem like they're available anywhere. Tried running $ sudo fc-cache -f ~/.guix-profile/share/fonts/truetype but that didn't help either. Any idea what I'm doing wrong?
Re: guix build python2 --with-source fails?
Simon,
zimoun 写道：
Why is it not possible to use '--with-source' with the package
python2?
λ mv tmp/{Python,python2}-2.5.2
λ guix build python2 --with-source=/tmp/python2-2.5.2
substitute: updating substitutes from
'https://guix.tobias.gr'... 100.0%
substitute: updating substitutes from
'https://ci.guix.gnu.org'... 100.0%
^C
Guix expects the source directory to start with the package NAME.
There's a very recent bug report asking to support arbitrary
--with-source=NAME=FILE.
Kind regards,

guix build python2 --with-source fails?
Dear, As an exercise about rebuilding old versions (e.g. used by old scientific paper), I have tried to rebuild say the very old Python 2.5. My naive attempt is to start with: --8<---cut here---start->8--- wget https://www.python.org/ftp/python/2.5.2/Python-2.5.2.tgz tar -xzvf Python-2.5.2.tgz guix build python2 --with-source=/tmp/Python-2.5.2 guix build: warning: transformation 'with-source' had no effect on python2@2.7.17 The following graft will be made: /gnu/store/ck7swzbk6h7mc7splsih93xsixc6z4ni-python2-2.7.17.drv [...] --8<---cut here---end--->8--- Why is it not possible to use '--with-source' with the package python2? I was expecting fail to build, not fail to apply the transformation. I mean, I thought that "guix build foo --with-source" was somehow equivalent to: --8<---cut here---start->8--- cd /tmp/Python-2.5.2 guix environment -C python2 ./configure make --8<---cut here---end--->8--- which works. Is it not? Thank you in advance. All the best, simon
