I recently started using pipenv instead of requirements.txt, and I can use this just fine with pyside2 by specifying it like so in my Pipfile:
[source] url = "https://download.qt.io/snapshots/ci/pyside/5.9/latest" verify_ssl = true name = “qt" "pyside2" = {version = "*", index = "qt”} [pipenv] allow_prereleases = true
I run pipenv install —pre and then I lock using pipenv lock --pre. Everything works just nicely from my Windows machine.
I then add Pipfile and Pipfile.lock to source control and move onto my macOS machine. When I, on the mac, run pipenv install —pre I get an error that a matching version of pyside2 cannot be found.
$ pipenv install --pre Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creatingits own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead.

When I go look inside of http://download.qt.io/snapshots/ci/pyside/5.9/latest/pyside2/ I can see that on Windows, the wheel named 5.9.0a1.dev1527520955 got installed. For macOS, there is no such wheel available. Instead, on macOS, the wheel is called 5.9.0a1.dev1527520119.
When I go into other folders (not the "latest" one), I can see all wheels are using unique numberings.
I'm guessing that this is a problem when using pipenv/Pipfile but I don't know if this is just because of the CI and that maybe this is not how the naming will be done once PySide2 goes stable and is officially released... but I wanted to raise a flag well in time for that about this issue - so the wheel naming will be adressed in time for tech preview/release.
I believe this applies to all branches of PySide2, not just the 5.9 one which I tagged here.
