pyobjc 10.3: `module 'objc' has no attribute 'registerNewKeywordsFromSelector'` #611

Where is registerNewKeywordsFromSelector meant to be defined? What am I missing?

% python -c "import Quartz"

What versions of the various pyobjc packages are installed? This looks like having an older version of pyobjc-core installed.

I fully expected this to be an embarrassing case of me messing up somewhere. And it indeed it was, a typo: https://github.com/Xpra-org/gtk-osx-build/commit/b429c6ad3112d50bd20f9e1d3efaccf3e369815b Sorry for wasting your time!

FYI, this came about because the packages on pypi use a different spelling: https://github.com/Xpra-org/gtk-osx-build/commit/eead1526ba22357098808ad66875632231c0dc47 Which may have happened when we switched to the short URLs (I haven't checked): https://github.com/Xpra-org/gtk-osx-build/commit/78190541252a6de85f0558112dad2b5d6de4b585

That's the filename normalisation used for distribution archives which escapes some characters, such as a minus sign, in distribution names when calculating the archive filename for a distribution artefact (see https://packaging.python.org/en/latest/specifications/binary-distribution-format/#escaping-and-unicode for more details on this)
