Installation of dependencies failed, tool unusable

[ygoe]

I recently had to reinstall Python for Windows because something in it broke completely by itself. I have no clue what it was but the other tool I use that requires Python is working again. I used the current official recommended install manager from the Python website.

Now I needed to run pymcuprog again and, of course, it didn't work anymore. Some package was missing. So I installed all of its dependencies again and one of them seems to fail. The output is very extensive and I don't understand what's going on. My Python knowledge is very basic and I'm unable to debug such errors.

So here's my environment first:

• Windows 11 x64
• Python 3.14.0 from install manager
• pymcuprog based on commit dbd4904 from 2024-03-22 (I made some extensions, but that's not the issue here)

I have these two files:

• install.cmd
• requirements.txt

First, the requirements files has this content:

pyserial
IntelHex
PyYAML
appdirs
pyedbglib>=2.24

And install.cmd does this:

cd /d "%~dp0"
python -m pip install -r requirements.txt
@pause

And here's the full output of the desaster:

(Sorry, colours are not visible here.)

So something in the dependency "hidapi" that apparently was built from C code didn't work. There are notices, warnings and errors in this output. I can't really tell them apart.

What do I need to do to make this Python-based tool usable again? Can I also use pymcuprog without relying on Python because that regularly causes trouble?

Hi ygoe

The short answer to your last question is: Download the compressed Windows iotprovision binary from the repo https://github.com/microchip-pic-avr-tools/iotprovision-bin , extract the Windows binary, and rename it to pymcuprog.exe. The README in the repo gives the technical background.

[ygoe]

Thank you, this has helped for now.

I'm still curious how the issue could be resolved. I made some changes to the pymcuprog tool a while ago (#46) and would like to keep them for one of my projects that needs it. But it doesn't look like Microchip is really interested in community contributions or open source in general.

With 3.13.9, the installation under Windows is successful. With 3.14.0, the hidapi installation fails the same way as it did in your case.

As far as I understood it, Microchip has published its in-house software in this repo in order to allow people like me to make use of it (PyAvrOCD), but they are not interested in PRs.

HIDAPI does not have a binary build for python 3.14 (yet) which means that if you run 3.14 it will try to build it itself. This works [usually] on Linux machines where build systems are part of the distro, but Windows has little chance of building anything automatically. Best use 3.10->3.13 until someone™️makes a build for the hidapi package and bundles it.
