git-cola @3.1 fails to launch

[odysseus9672 (Sean Lake)]

When I try to launch git-cola in the command line I get the following error

Seans-Work-Macbook-Pro:FASTView sean$ git-cola
Traceback (most recent call last):
  File "/opt/local/bin/git-cola", line 55, in <module>
    from cola.main import main

    from . import app

    assert API in (PYQT5_API + PYQT6_API + PYSIDE2_API + PYSIDE6_API)
AssertionError

This looks like it might actually be a bug in py36-pyqt4 @4.12.1_3.

git-cola +qt5 is not affected by this error.

support for Qt4 was removed in the latest py-qtpy release (v2.0) - I guess it's time to remove the qt4 variant from the git-cola port.

[edit: I see the `git-cola` port could be updated, but also that it vendors the `qtpy` package. So to keep full compatibility with what upstream supports, I guess the port could use the internal `qtpy` version instead of using MacPort's own port. I'll leave that to the maintainer to decide]

[reneeotten (Renee Otten)]

port updated in this commit - no longer uses Qt4.

Git-cola still fails to launch for me. Should I open another ticket? Now the error text reads:

Seans-Work-Macbook-Pro:~ sean$ git-cola

You do not seem to have PyQt (or PySide) and qtpy installed.
Please install the PyQt (or PySide) and qtpy into your Python environment.

For example, on a Debian/Ubuntu system you can install these using apt:

    sudo apt install python3-pyqt5 python3-pyqt5.qtwebkit python3-qtpy

For the record, I have the following installed:

  py311-pyqt5 @5.15.9_0 (active)
  py311-pyqt5-sip @12.11.1_0 (active)
  py311-qtpy @2.3.0_0 (active)

so I'm not sure what additional package I should install. Is there a missing dependency, or is this just a bug?
