@nipsky looks like some new incompatibility with python 3.13 - I was able to reproduce. Unfortunately the only feasible method at the moment is to run in a virtualenv using python 3.9-3.12. Upstream is working on 3.13 support but it's not quite there yet.

To be honest, we'll probably be on 3.14 by the time they support 3.13. I'll try have a look to see if I can patch it to initialize, but this week is kind of busy for me so it wouldn't be quick.

Need to add python-cbor2 dependency.

And yep currently borked, need this PR https://github.com/vllm-project/vllm/pull/13164 it was recently approved so I think in next release it will work :)

@nipsky i was suggesting you use pip/conda/etc (from within your venv) to install as it exists on pypi - https://pypi.org/project/vllm/

installing this package will only try build it for current system python

nipsky commented on 2025-08-04 12:11 (UTC)

@envolution Thanks for the tip, I’ve tried this with a couple of older Python versions (3.9 to 3.12) within fresh Conda environments but got the exact same error for each. Or do I need to rebuild the package with Python <3.13 somehow?

Installation works fine, but running vllm gives me this error:

For CPU, this is missing certain dependencies (all of which can be found either in the official repo or AUR):

python-prometheus-fastapi-instrumentator python-python-multipart python-partial-json-parser python-watchfiles python-gguf python-triton python-cloudpickle

Would be great if those can be added to the dependency list.

envolution commented on 2025-03-28 16:30 (UTC)

@amstan thanks for the report, there were a handful of dependencies not caught by namcap. FYI this package targets CPU, it's possible it detects and links for rocm correctly, but ideally a separate package like python-vllm-rocm (similarly to python-vllm-cuda i used to maintain) should be created due to lack of flexibility in the pacman subsystems (we can't elegantly detect and modify dependencies based on GPU architectures/packages installed on the host system).

If this new pkgrel works on rocm, please add a comment for others to become aware.

Compiles to the end, but then:

If you get some weird compilation error(/lib/cmake/hip/hip-targets.cmake not found) and you want to do rocm, make sure you don't have hip-runtime-nvidia installed.

amstan commented on 2025-03-28 05:37 (UTC)

Seems to be missing python-setuptools-scm.
