Debian's python3-webassets package [1] comes from a different upstream [2] than Gentoo's [3], which is almost 5 years old. It might be advisable to switch. [1] https://packages.debian.org/de/sid/python3-webassets [2] https://github.com/miracle2k/webassets [3] https://launchpad.net/web-assets
The new upstream officially supports Python 3. Just adding PYTHON_COMPAT=python3_3 to the 0.1.1-r1 ebuild *seems* to work, but I never actually tested it.
Created attachment 373496 [details] webassets-0.9.ebuild (In reply to Dennis Schridde from comment #1) > Just adding PYTHON_COMPAT=python3_3 to the 0.1.1-r1 ebuild *seems* to work It does not, www-apps/nikola-6.4.0 does not recognize it: WARNING: Nikola: In order to USE_BUNDLES, you must install the "webassets" Python package. Release notes for version 0.9: webassets now support Python 3, and drops support for Python 2.5. This (webassets) repository has a similar name, but appears not to be derived from the Launchpad web-assets repository, so I propose to use a new name in Gentoo. Please find an ebuild for the proposed www-apps/webassets-0.9 package attached.
Committed. Thanks!
