Not yet ready for merge. I still have to investigate why running qutebrowser yields

qutebrowser needs QtWebKit or QtWebEngine, but neither could be imported!
The errors encountered were:
QtWebKit: cannot import name 'QtWebKit' from 'PyQt5' (/nix/store/5prasyaxrbcy43rdyq0zydgc1ap2l8dl-python3.7-pyqt-5.12/lib/python3.7/site-packages/PyQt5/__init__.py)
QtWebEngine: cannot import name 'QtWebEngineWidgets' from 'PyQt5' (/nix/store/5prasyaxrbcy43rdyq0zydgc1ap2l8dl-python3.7-pyqt-5.12/lib/python3.7/site-packages/PyQt5/__init__.py)

According to https://www.riverbankcomputing.com/news/pyqt-512, "the QtWebEngine, QtWebEngineCore and QtWebEngineWidgets modules have been moved to a separate PyQtWebEngine package." I'm currently packaging that one.

Now I'm getting

Fatal error: PyQt5.QtQml is required to run qutebrowser but could not be imported! Maybe it's not installed?

The error encountered was:
No module named 'PyQt5.QtQml'

Please search for the python3 version of PyQt5.QtQml in your distributions packages, or see https://github.com/qutebrowser/qutebrowser/blob/master/doc/install.asciidoc

That's still true when merging #56349.

I really don't see any configure option to fix this :(

Could you rebase?

Done. Note there's a new version out. However, I currently don't have time to look into this any further or work on nixpkgs at all.

That, and version 5.12 doesn't exist anymore — you need 5.12.1

Hah, the lack of version in path, compounded by the availability of the new version, tripped me up.

This can probably be fixed by adding more options into pkgs/development/python-modules/pyqt/5.x.nix. It depends on qtbase, but not qtdeclarative.

So I tried to contiue this by updating pyqt to 5.12.2 and pyqtwebengine to 5.12.1 since old versions are not available anymore. I can not make pyqtwebengine compile:
mkdir: cannot create directory \u2018/nix/store/4c4ajgdnhlqk994hilagk5cgv7vw9yzg-python3-3.7.3/lib/python3.7/site-packages/PyQt5\u2019: Permission denied
I've had some really annoying bugs in qutebrowser lately, which is why I really want this update, so I can see if the mismatched pyqt version is at fault.
