Installation fails about selectolax HOT 10 CLOSED

You need to fill an issue to ghtopdep, because it requires 0.1.x version of selectolax and it's pretty old. Python 3.9 has some breaking changes in API so that's why you can't compile an old version of selecolax on a new Python version. When you compile it locally from the repo, it regenerates all the C code as well.

The easy workaround for your problem is to pip install Cython>=0.29.23 before installing ghtopdep on a new environment. This will force code regeneration even when you try to install an old version of selectolax.

I faced into it with Python 3.9 on Ubuntu.

I think you just need to update Cython. There are precompiled binaries for the most common platforms.

Thanks for your response, I have the latest version of cpython installed (via pip). Here is a reproducible:

Originally reproducible via ghtopdep:

docker run -it python:3.9 /bin/bash
git clone https://github.com/github-tooling/ghtopdep
cd ghtopdep
python setup.py install
pip install -e .

Expected: works
Actual: I get the stack-trace with selectolax/parser.c:9859:60: error: ‘PyTypeObject’ {aka ‘struct _typeobject’} has no member named ‘tp_print’; did you mean ‘tp_dict’?

When building the wheel also on such a Docker container and copying into the other container, installing it, then it works.

docker run -it python:3.9 /bin/bash
git clone --recursive  https://github.com/rushter/selectolax
cd selectolax
pip install -r requirements_dev.txt
python setup.py install
python setup.py bdist_wheel
# Copy the following file into the other container, then it works:
# /selectolax/dist/selectolax-0.2.11-cp39-cp39-linux_x86_64.whl

So I would guess, that something when compiling/releasing and publishing to Pypi is not configured correctly. Will investigate further.

I saw 7e49aff, seems like that could fix it since their changelog contains some related fixed.

I've made a new release with more builds.
You can also try running python setup.py install --cython

from selectolax.

Is unfortunately still reproducible. These are the reproduce steps:

docker run -it python:3.9 /bin/bash
git clone https://github.com/github-tooling/ghtopdep
cd ghtopdep
python setup.py install
pip install -e .

The error will come in the last pip install -e . command. I ensured a new Docker container + pinned the version to your recent version to ensure its not a caching problem.

When building selectolax directly via the repository it works, so there seems still something odd going on with the wheels.

Yeah in my case this was also during installation of ghtopdep. I guess we can close the issue if this is about old version of selectolax, because in that case there is nothing to do here, ghtopdep really needs to just update its dependencies.

from selectolax.

Let me update an upstream issue and thanks @rushter for your effort in upgrading the release infra.

Upstream issue: github-tooling/ghtopdep#15
