Getting the following errors when trying to run the "pip install -r requirements.txt" command in MSYS MinGW64, how do I fix it?

It's possible that my requirements.txt is out of date.
For example, I believe pyGObject is now up to 3.50.0 (at least per Homebrew). Try using that instead.

[Route66Fan]

Ok, I'll try that out.

Thank you!

I've just updated requirements.txt in Code.

I tried using the updated requirements.txt file & now I am getting a different error message:

Actually, this could be several errors in pip as well as python - and I'm learning to love python as much as I 'love' java from an ease of maintenance standpoint. Python's already up to 3.13, as I just found out by upgrading to Fedora 41.

As such, I can almost guarantee that things are deprecated out of Python 3.11, as much as they may not be ready for primetime in 3.13. This was a problem when 3.12 was introduced (had no python-dateutils available), and may be a problem again. Try building gr-osmosdr when Linux has moved you to 3.13, and the pybind11 makefile rigidly needs the includes for 3.12.

More specifically in your case, It looks like ninja has an issue building in 3.11. You could try killing 3.11 and moving to 3.12, then reinstalling all the dependencies there, or setting up a virtual python environment via venv.

Secondly, I see you're trying to do this under MSYS in Windows, which I've never gotten to work reliably.
