Description Iryna Shcherbina 2018-02-19 16:17:14 UTC

The python3-scss (1.3.4-12.fc28) RPM requires both Python 2 and Python 3:

$  dnf --disablerepo=* --enablerepo=rawhide repoquery --requires python3-scss | grep python
/usr/bin/python2
/usr/bin/python3
libpython3.6m.so.1.0()(64bit)
python(abi) = 3.6
...

This happened due to recently introduced shebangs mangling [0], and you might see the warnings in the build log:

> + /usr/lib/rpm/redhat/brp-mangle-shebangs
> *** WARNING: mangling shebang in ./usr/lib64/python3.6/site-packages/scss/tool.py from #!/usr/bin/env python to #!/usr/bin/python2. This will become an ERROR, fix it manually!

The executable contains `#!/usr/bin/env python` shebang, which is forbidden by the guidelines and is automatically mangled to `#!/usr/bin/python2` during build. Please fix the shebang to be `#!/usr/bin/python3` explicitly [1] or remove the executable bit from the above file if not needed.

If anything is unclear, or if you need any kind of assistance, you can
ask on IRC (#fedora-python on Freenode), or reply here. We'll be happy
to help investigating or fixing this issue!

Comment 1 Fedora End Of Life 2018-02-20 15:37:56 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 28 development cycle.
Changing version to '28'.

Hi Patrick,

I have prepared a PR that fixes the problem:

https://src.fedoraproject.org/rpms/python-scss/pull-request/2

May I ask to review and rebuild the package?

Comment 3 Patrick Uiterwijk 2018-03-20 10:08:03 UTC

Hi, thanks for the patch.
I've applied it, and rawhide build is done.
