Feeling really stupid, right now, but the title says it all:
How do you start the QtDesigner?
pip and I believe to have identified the directory it’s been installed in as
Now what? There are a lot of .pyd files, some .dll’s, too, but nothing executable (well, except a
...\site-packages\PyQt5\Qt\bin, but that doesn’t sound like what I’m looking for.
The latest PyQt5 wheels (which can be installed via pip) only contain what’s necessary for running applications, and don’t include the dev tools. This applies to PyQt versions 5.7 and later. For PyQt versions 5.6 and earlier, there are binary packages for Windows that also include the dev tools, and these are still available at sourceforge. The maintainer of PyQt does not plan on making any further releases of such binary packages, though – only the runtime wheels will now be made available, and there will be no official wheels for the dev tools.
In light of this, someone has created an unofficial pyqt5-tools wheel (for Windows only). This appears to be in it’s early stages, though, and so may not keep up with recent PyQt5 releases. This means that it may not always be possible to install it via pip. If that is the case, as a work-around, the wheel files can be treated as zip files and the contents extracted to a suitable location. This should then allow you to run the
designer.exe file that is in the
Finally, note that you will also see some zip and tar.gz files at sourceforge for PyQt5. These only contain the source code, though, so will be no use to you unless you intend to compile PyQt5 yourself. And just to be clear: compiling from source still would not give you all the Qt dev tools. If you go down that route, you would need to install the whole Qt development kit separately as well (which would then get you the dev tools).
