Looks like https://stackoverflow.com/questions/77476433/importerror-cannot-import-name-... Fedora 39 has: python-cssselect-1.1.0-6 Have a look at the https://github.com/scrapy/scrapy/issues
You should give enough details so others can reproduce the issue: how did you install scrapy, which version of Fedora, scrapy, and python-cssselect do you have?
There are problems with the Fedora package:
Available Packages Name : python3-scrapy Version : 2.10.1 Release : 1.fc39 Architecture : noarch Size : 659 k Source : python-scrapy-2.10.1-1.fc39.src.rpm Repository : fedora Summary : A high-level Python Screen Scraping framework URL : https://scrapy.org License : BSD Description : Scrapy is a fast high-level screen scraping and web crawling : framework, used to crawl websites and extract structured data : from their pages. It can be used for a wide range of purposes, : from data mining to monitoring and automated testing.
Here, on Fedora 39:
% doas dnf install python3-scrapy doas (gnw3@imacf39) password: Last metadata expiration check: 0:04:29 ago on Wed Feb 7 10:39:54 2024. Error: Problem: conflicting requests - nothing provides (python3.12dist(twisted) < 23.8~~ with python3.12dist(twisted) >= 18.9) needed by python3-scrapy-2.10.1-1.fc39.noarch from fedora (try to add '--skip-broken' to skip uninstallable packages)
twisted has https://nvd.nist.gov/vuln/detail/CVE-2023-46137 so
Many large Python systems have not been ported to python-3.12. I've had success using fedora's python-3.11 in a conda environment. Anaconda python is also a way to run stuff that still needs python 3.10 or 3.11.
So yes... just tried something totally different (opening an IFC file with FreeCAD) and the importer stops saying:
" File "/app/lib/python3.11/site-packages/ifcopenshell/__init__.py", line 62, in <module> raise ImportError("IfcOpenShell not built for '%s'" % python_distribution) <class 'ImportError'>: IfcOpenShell not built for 'linux/64bit/python3.11' "
Back to scrapy I am using F39 updated to the latest everything, I installed using the given instructions on their website which is pip install scrapy scrapy is version 2.11.0 cssselect is version 1.1.0
So should I file a bug somewhere or patiently wait (it's been like for over a month at least)?
Thank you.
