PYYAML hates me and my Flatpak project

1

So, I’m attempting to make a Flatpak of the Amulet Minecraft Map Editor. I feed my requirements.txt to flatpak-pip-generator, save the output (in YAML) to amulet.yml, and run this:

flatpak-builder --sandbox --user --install-deps-from=flathub --mirror-screenshots-url=https://dl.flathub.org/media/ --add-tag=0.10.35 --bundle-sources --repo=amulet_flatpak_repo amulet_build_dir amulet.yml --force-clean

And it after a while, it fails on pyyaml:

Can anybody tell me why PyYAML hates me?

Edit: I wasn’t spamming. I was asking for help.

Seems like an issue with the order. It’s probably trying to install pre-commit before installing pyyaml, but the former depends on the latter.

I’ll switch up the order then and see what happens.

Using my new requirements.txt, I have a new amulet.yml. and I’m still up against the wall:

This time I manually edited amulet.yml to fill out the pyyaml section and ran with the --verbose flag to see if I could get anything more useful.

Before:

  - name: python3-pyyaml
    buildsystem: simple
    build-commands:
      - pip3 install --verbose --exists-action=i --no-index --find-links="file://${PWD}"
        --prefix=${FLATPAK_DEST} "pyyaml~=6.0" --report=pip_report.json --no-build-isolation
    sources: []

After:

  - name: python3-pyyaml
    buildsystem: simple
    build-commands: 
      - pip3 install --verbose --exists-action=i --no-index --find-links="file://${PWD}"
        --prefix=${FLATPAK_DEST} "pyyaml==6.0.2" --report=pip_report.json --no-build-isolation
    sources:
      - type: file
        url: https://files.pythonhosted.org/packages/6b/4e/1523cb902fd98355e2e9ea5e5eb237cbc5f3ad5f3075fa65087aa0ecb669/PyYAML-6.0.2-cp310-cp310-manylinux_2_17_x86_64.manylinux2014_x86_64.whl

Edit: There’s a ton of info on pypi.org and I don’t know if it’s being somehow missed or just ignored but even my manual override failed.

Edit 2: I don’t know why this was flagged as spam. I didn’t do anything spammy.

Freedesktop SDK has python 3.11, you are using a wheel for python 3.10

If you want to use wheels choose the correct one https://files.pythonhosted.org/packages/67/a4/1f5fbd3f58d4069000522196b0b776a014f3feec1796da03e495cf23532d/lxml-5.3.0-cp311-cp311-manylinux_2_17_x86_64.manylinux2014_x86_64.whl

Or use the sdist https://files.pythonhosted.org/packages/e7/6b/20c3a4b24751377aaa6307eb230b66701024012c29dd374999cc92983269/lxml-5.3.0.tar.gz

lxml isn’t pyyaml but I see from your example how they’ve included the Python version as part of the filename, which I didn’t realize. Or just didn’t see.

We’ll try again with

    build-commands:
      - pip3 install --verbose --no-index --find-links="file://${PWD}" --prefix=${FLATPAK_DEST}
        "pyyaml==6.0.2" --report=pip_report.json --no-build-isolation

Ah yea I was thinking about something else and misread it for pyyaml.

Thanks to you pointing out the fact that I was calling version, after correcting it, we’re back in business and no more crashing!

I still don’t know why it wasn’t able to do it itself, but that’s something I can look at later, now that it’s working.

Why was this thread flagged as spam?!

I would think pastebin would be exempt from that rule, given how instrumental it is in keeping posts looking clean and tidy, but I’ll be mindful of this going forward.
