PyQT5 is actually packaged, and I was just being lazy in my comment. It's actually pyqtchart and qscintilla that are the problems. They're not packaged for nix and won't install in a virtualenv with pip. Something to do with hardcoded paths for dependencies I think. I'm going to have a go at writing a nix files that build them from source, with the help of a NixOS expert, so we'll see how that goes.
