AttributeError: preprocessors
"xml.etree.cElementTree" was a deprecated alias for "xml.etree.ElementTree" for a long time and it's removed in the 3.9. https://github.com/python/cpython/blob/3.8/Lib/xml/etree/cElementTree.py
python-defusedxml FTBFS for the same reason so the fix has to be done there: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/build/1321088/
Thanks Lumír for the investigation. Fixed in nbsphinx/nbconvert. |
python-networkx fails to build with Python 3.9.0a5. Exception occurred: File "/usr/lib/python3.9/site-packages/IPython/utils/shimmodule.py", line 94, in __getattr__ raise AttributeError(key) AttributeError: preprocessors The full traceback has been saved in /tmp/sphinx-err-hjoy6jwj.log, if you want to report the issue to the developers. For the build logs, see: https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01321097-python-networkx/ For all our attempts to build python-networkx with Python 3.9, see: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/python-networkx/ Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.9: https://copr.fedorainfracloud.org/coprs/g/python/python3.9/ Let us know here if you have any questions. Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9. A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon. We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.
