Has the python qt installation story improved much recently? A few years ago it was a pain to set up, especially within a virtualenv, which was one of my only complaints with it. Everything else was wonderful.

You can just do `pip install PyQt5` now. That is possible without a virtual environment, but in practice I think you still want to use one: python3 -m venv venv && source venv/bin/activate && pip install PyQt5.

  How well does that work on OSX? I’ve tried many times over many years, but never got a satisfactory working Python + Qt development environment working on the Mac.

    conda install pyqt

      Why was this downvoted? It will setup exactly what was asked for. Specifically qt 5.9.5 with PyQt.

    With Python3 and PyQt5 it is literally as simple as "pip install pyqt5". I speak from having built and maintained multiple PyQt-based apps on MacOS. Edit: I should say, there are MacOS-unique difficulties if you want to bundle your nice PyQt5 script into a standalone MacOS app bundle using PyInstaller. But that's a separate issue.

  pip installing binary dependencies! What could go wrong?

      Mix of dynamic libraries, missing libraries, mismatch between libc versions. Requirements for a c compiler to be available. But all of these things have improved greatly, in my recent experience.

    With the new binary wheels, this actually works now - at least on Windows 10 and misc Linux distros (and according to other comments here, on Mac OS too). On Linux you might want to get the distros qt/qt-dev packages, as usual. But as far as I can recall, you generally don't have to.

      Great - installing random (huge) binaries that have been compiled god-knows-how by god-knows-whom expecting god-knows-what other libraries to be on the target system.
