Is it possible to use the Qt Designer in PyCharm with all the most recent versions?
I use Python 3.7.0 and PyQt5 (5.11.2) in PyCharm and have downloaded the PyQt5Designer package (using PyCharm), but there seems to be no usable designer.exe file in the PyQt5 directories, and I cannot find any PyCharm functionality to start the designer either. Also, pyqt5-tools seems to be incompatible with Python 3.7.0, so that folder does not exist either.
I tried to use PyQt5 with 3.7, and realized the same issue. I downgraded Python to 3.6, and all was good.. I'd recommend downgrading until a new version of PyQt is released to support 3.7.
Inside of the pyqt5-tools, after installation will have the designer.exe you can use.
