With SIP v4.19.4 and PyQt 5.9 on Linux,  code like this breaks:

buttonBox = QDialogButtonBox(
    QDialogButtonBox.Cancel | QDialogButtonBox.Ok | QDialogButtonBox.Help
)
self.helpButton = buttonBox.button(QDialogButtonBox.Help)  # type: QPushButton

As far as I can tell, that code is correct. Unfortunately with
sip==4.19.4, self.helpButton is assigned the value None, instead of
the QPushButton. Moreover, the
QPushButtons do not appear to the user, so it seems they're never
actually created when the QDialogButtonBox is instantiated.

The problem is that when you install PyQt5.9 from PyPi, by default it
installs SIP 4.19.4, not SIP 4.19.3. When SIP is downgraded to 4.19.3,
the code works as expected.

Unfortunately in the requirements.txt for my application, a specific
sip version is not specified. So currently I'm getting bug reports
from unhappy users reporting broken code.

Phil, do you have an ETA for PyQT 5.9.1 for Linux on Pypi? Until it
does show up, is it possible to tell Pypi to install sip 4.19.3 when
installing PyQt5.9?

Thanks,

Damon
