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. -- George N. White III
