Hi, this is from the openSUSE build service: https://build.opensuse.org/package/show/home:bnavigator:sip5/qutebrowser The linked build log [qutebrowser_sip5_log.txt](https://github.com/qutebrowser/qutebrowser/files/5358888/qutebrowser_sip5_log.txt) should list everything about the build environment.

Yes, these are [VMs](https://build.opensuse.org/monitor) The failure was on lamb24. You can also run the chroot environment on a local machine. Would have to check if the flakyness occurs on those...

@arunpersaud's error is because pytest is run with a `numcodec` source directory in the `PYTHONPATH` before the `numcodec` module directory with the compiled extensions.

It's a downstream issue and was fixed here through using the `--pyargs numcodecs` parameter for pytest: https://build.opensuse.org/request/show/1058132

Downstream Gentoo's patch fixes it.

#33 is the better fix
