Dear fellows, I have some troubles with two sphinxcontrib packages (but others are likely similar). Since a few weeks , the builds, actually the docs, fail with: [ 99s] + pushd docs [ 99s] ~/rpmbuild/BUILD/sphinxcontrib-asyncio-0.3.0/docs ~/rpmbuild/BUILD/sphinxcontrib-asyncio-0.3.0 [ 99s] + PYTHONPATH=.. [ 99s] + make html [ 99s] sphinx-build -b html -d _build/doctrees . _build/html [ 100s] Running Sphinx v4.4.0 [ 100s] [ 100s] Extension error: [ 100s] Could not import extension sphinxcontrib.asyncio (exception: No module named 'sphinxcontrib.asyncio') [ 100s] make: *** [Makefile:56: html] Error 2 [ 100s] error: Bad exit status from /var/tmp/rpm-tmp.TJFdic (%build) While the PYTHONPATH is set correctly, the problem is, that the module sphinxcontrib is loaded from the sitelib. There, no asyncio sub-module exists and the loading of sphinxcontrib.asyncio fails. Maybe this is due to changed Python behavior of finding modules? I haven't seen anything related in the Python changelogs however. Does anyone has an idea how to circumvent this issue, or a best practice? cheers, Sebix
